A Bellevue man says his cell phone service provider is the one getting the wrong number, the number appearing at the bottom of his bill.

When John Kirby got a second Sprint phone to call his fiancée, he never expected to ring up a $400 bill for one month. “I pay my monthly bill like I'm supposed to because I'm getting service, but it’s that extra thing they've goofed up on and they won't own up to it.”

Kirby says the second phone on his account had been costing about $80 a month since October. Then came May's bill.

Fact Finders contacted Sprint to find out why this second phone with minimal charges for six months suddenly had a monthly bill of $400. Sprint said it can't comment on a customer’s bill, but customer service will investigate the complaint.

Kirby hopes he gets an answer soon because he refuses to pay the increase and received a past due notice. “They should put it back to normal and find out what computer is messing up.”

The $400 bill comes from nearly 1,000 anytime minutes charged at 45 cents a minute. That has Kirby saying wait a minute, that's not the plan he signed up for. “I don't want to have to pay for something that is not valid.”

The Sprint customer says a similar mistake occurred with roaming charges on a previous bill. He received an apology and credit for that. Sprint has yet to tell Kirby why the unexpected charge showed up again.
