Two years ago, Sharon Mandell and her husband switched their mobile wireless service from AT&T to Xfinity. In the process, Mandell exchanged her old phone for a new one. Her husband’s phone was too old to be exchanged, so he simply stopped using it when he got a new one.
For a long time, she suspected Xfinity was overbilling her, but it was hard to decipher the complex bills she received, especially because she also had charges mixed in for internet and video services.
Finally, in March she went to the Xfinity store in Framingham to get an explanation of her bill.
Mandell, who is in her 70s and lives in Bolton, said a young Xfinity representative at the store studied her bill for a while and then announced, “Something’s not right.”

The representative explained that Mandell was billed for four phones, not two, for an extra $60 per month. The old phone Mandell had exchanged? She was still paying for service on it. And her husband’s? He had left it in some forgotten corner of the house. But she was paying for service on it too.
Xfinity’s erroneous monthly billing, dated to 2023, meant she had paid an extra $1,200 for two phones not in use.
The representative urged her to insist on a credit for $1,200, Mandell told me in an email asking for help.
But Mandell’s demands for a credit were stymied by what Xfinity called its “120-day rule” — that it could give wronged customers credits only for the most recent three months, no matter how far back the overbilling began. That limited her refund to $180.

Mandell protested but Xfinity dug in its heels, even saying the overbilling was her fault.
“It was mind-boggling that they would bill us for phones that were clearly not in use,” she said. “And then they refused to give us a credit.”
The resolution: I wrote to Xfinity with a copy of Mandell’s detailed and lucid account of what happened, saying I thought she had a “legit” complaint. The same day, Mandell got a call from Xfinity’s corporate office.
“I almost fell off my chair when Xfinity told me I would get a $1,200 credit,” Mandell told me.
Xfinity told me: “This should not have happened and we apologize.”
The takeaway: The 120-day rule I found on Xfinity’s website applies to the purchase or rental of movies and TV shows when customers encounter technical problems, but there was no indication it applies to phone service. Should Mandell be penalized for not discovering the discrepancy earlier? Billing accuracy should have been Xfinity’s responsibility, not hers.
Mistakes happen. What I fault Xfinity for is not immediately admitting its mistake and making Mandell whole. Xfinity got paid for something she didn’t ask for, didn’t want, and didn’t get. It would be improper for Xfinity to profit from its mistake.
The lesson in all this? When you know you are right, persist, persist, persist. And don’t be dissuaded by some silly “rule” thrown in your way.
Future of Direct File?

I’m a big fan of Direct File, the online federal income tax filing system that’s free. It got rave reviews from users after being tested in 12 states last year and was expanded to 25 states for this year’s tax filings. For anyone filing a fairly simple tax return, it means saving the $100 or more you would pay a commercial tax preparation company such as TurboTax or H&R Block.

But the Internal Revenue Service is going through some big changes under the Trump administration. About one-third of its 100,000 employees are expected to resign or be laid off by the end of the year.
One of the casualties may be Direct File. The Associated Press reported last week that the program will be eliminated, citing two people familiar with the decision. So stay tuned.
More National Grid confusion

Last winter, National Grid failed to send timely bills to about 35,000 customers in Massachusetts, prompting the Department of Public Utilities to scold the state’s second-largest gas utility and order it to write off millions of dollars in charges.
National Grid publicly apologized for its administrative lapse and quickly agreed to write off amounts owed for the oldest periods when customers got no bill. For example, customers who went six months without being billed would be required to pay what they owed only for the most recent two months.
But apparently some customers nevertheless got billed for the full amount, prompting one reader to write to me asking for clarification.
“We just received a $2,138.31 bill for five months of charges going back to Nov. 1,” the reader wrote. “Should I contact National Grid or just ‘suck it up’ and pay the total when we can?”
No, don’t pay the full amount, I replied. It’s a mistake. Call National Grid and cite the DPU order.
In an email to me, National Grid reiterated its commitment to the write-off and said it would communicate directly with impacted customers. I ask who would ultimately pay for the write-off — ratepayers or shareholders?

“That will be reviewed and determined at a future date,” a spokesperson said.
Refund in loan at exorbitant interest rate

Last month, I wrote about a reader who contacted me about an online lender called Clear Air that charged his adult son 725 percent interest on a $500 short-term loan. The reader complained that Clear Air took advantage of his 52-year-old son, who has schizophrenia and lives on Social Security disability benefits.
The father said his son took the loan without his knowledge, then came to him for help when he struggled to keep up with the interest-only payments of $150 every two weeks.
After the column was published, Clear Air refunded the son $728.50 in interest and fees, according to the father.
“We’re quite grateful to have this resolved,” said the father, who asked that neither he nor his son be identified in this column, to protect the son from being a target of online scams.
