Received a bill stating I owed U.S. Cellular $187 from 3 years ago. I made sure that I didn't owe them anything when I took the phone back and cleared my account. There is nothing on my credit report about a U.S. Cellular bill either. After calling twice they still refuse to tell me anything besides that I owe that amount. They can't even tell me the date of the account or why it's apparently taken 3 years to bill me for a non existent account. Really believe it's a scam. I Refuse To Pay A Bill I DON'T owe.
