CHARLOTTE, N.C. - Marilyn Johnson was tired of her flip phone.
Her carrier, T-Mobile, signed her up, but for a family plan, not an individual one.
The difference: about $50 more each month. Roughly 10 months went by before Johnson noticed.
She said T-Mobile told her too much time had elapsed to refund the money.
So she contacted Action, who contacted T-Mobile.
“Maybe two days afterwards, I got a call from T-Mobile saying that they had gotten a call from you all and that they were ready to make a resolution,” Johnson said.
She got a refund of a debit card for more than $600.
"I had no doubt that Eyewitness News was going to help me get my resolution,” Johnson said.
The Better Business Bureau said check your bill every month.
"Dig down into that statement and be comfortable with each and every line that's in there,” said Tom Bartholomy with the BBB.
Johnson agrees, and said customers should pay more attention to bills than she did.
“You can see they gave me more than I asked for, so read the fine print,” she said.
She's used to details because she works in an insurance office.
If she missed something in her plan, she knows a lot of people can.
Some wireless companies try to sneak small charges into your bill.
It can be just a few dollars here and there.
Authorities call it cramming. It's another reason to check your bill carefully.
