i purchassed a samsung straight talk phone two weeks ago. I've tried to get it hooked up and it wont work. I've contacted walmart in faribault mn, where i got it from. They wont give me a different phone sence i have lost my reicept. I've spent many hours on hold at the 800 number given for support for the phone. I spent $150 on this phone and service. They have done nothing except sent me a new sim card that doesnt work. I've talked to countless support members, it seems like they cant fix my problem but wont admit it.
