RIDGEFIELD, Wash. — Online bill payments can make things easier for people, but technology has its issues and can also lead to easy mistakes.

Carol Doty thought she paid AT&T $57.84 last month.

"I was like, 'Oh my god.' I thought I was going to throw up at that moment. It was not $57.84. It was $5,784.00 that I overpaid because I accidentally moved the decimal point," said Doty.

Doty accidentally overpaid the company on Nov. 6. She contacted them about the mistake the very next day and has been getting the runaround ever since.

"At one point we were told we couldn't get that money back. That the amount was too large and we would have to keep it as a credit on the bill," said Doty.

Doty, who is on the account but not the primary account holder, said she's called the company, emailed, faxed and visited an AT&T store but still doesn't have her money.

"It is frustrating beyond explanation when you are talking to someone reading from a script who cannot help you. They are not helping you to resolve the issue," said Doty.

She's sharing her story so the company knows what a terrible customer experience she's had.

"I paid you too much money and I just want that money back," said Doty.

KGW Investigates, a NBC affiliate in Washington, reached out to AT&T. 

A corporate spokesperson said they issued a check Dec. 5 and they are working with a third-party vendor to process the refund as soon as possible but could not give a date of when Doty will get her money.

Doty has filed a complaint with the Washington Attorney General's Office.Â
