I purchased the sprint overdrive pro from best buy mobile on April 22. I used the device a couple of times, and decided I didn't want it. I returned it on May 7th, they refunded me my money and everything was all set. A week ago Some debt collectors called asking why I haven't paid my sprint bill, I told them I had no clue what they were talking about. They tried to say I owed like 300 something dollars, they claimed I did not cancel with in 30 days. They say the account was canceled on the 25th of May, but best buy has the records showing that I canceled with in two weeks. I've talked to about 10 different sprint customer service people, who don't know what the hell they are doing. Best buy has even talked to sprint, but all they said was your sol. I want to know what I can do, I know I only had the account for two weeks. I swear never again will I deal with sprint
