I have cancelled my Sprint data card service TWICE now and continue to recieve bills. The second time I called ( still very fresh in my memory ) I had to deal with a voicemail system that continually repeats itself and required me to enter my information so many times that I thought I would never speak to a person ( about 20 minutes before I was put on hold for a represenative ). When I finally spoke to a representative, she basically held me hostage on the phone for at least another 15 minutes while she informed me of all the many "oppurtunities" Sprint had for me. I repeatedly explained that I had continued to be billed after cancellation of my service, wanted nothing more to do with Sprint and wanted to stop being billed by Sprint. This being five months after I initially cancelled service, I no longer had my cancellation number to prove I had cancelled. I agreed to pay all money "owed" in order to cancel. After 45 minutes on the phone, I finally recieved a cancellation verification number. Before I hung up, I asked the representative one last time "Is the service off? Are you sure I have paid all that is owed and ever will be owed? The answer was yes and she assured me that I would never me billed again. Guess what? Yes, I have continued to recieve bills and now letters threatening to ruin my credit if I don't pay. If I take another hour out of my day to call them AGAIN, (can't cancel service online - If you could you would have a record of it and they clearly don't want that ) I can only assume that I will continue to be charged anyway. I have been telling many people about this issue and have found several others with almost identical experiences. It seems that this is no mistake but rather a conserted effort by Sprint to strong arm past customers into paying money they don't owe. By the way, if you try to hit zero in the voicemail to get to a representative sooner, it will hang up on you. It is clearly designed to try to out wait the caller. The recording the caller hears and the info the caller enters are identical for about the first five times. A caller could easily hang up thinking they were only going in circles until a new prompt to do with cancelling service shows up around the sixth time. I want to stress that I could not have been any more clear with the represntative ( I repeated my desire to never hear from them again many times ).
