Back last year in July 2008 I had gone into U.S. Cellular and paid my monthly bill of $82. My mistake was that for the first time I paid it in cash because I had not run by the bank to deposit the cash into my account. Two months go buy and I get my bill stating that I owe over double what I normally have to pay. Everyday I had collection agencies calling me saying I needed to pay this bill that I had already paid for in July. The person I paid the cash to had pocketed my money, and I didnt have the receipt to prove it. It taught me a huge lesson to never pay in cash and to really hold on to EVERY receipt.
