I purchased a Samsung from Assurance wireless about a year and a half ago. It has all the criteria needed for there service but they are telling me I can not use the phone and have to use the new one they sent me. However the new one they sent is garbage. Besides I paid them 200.00 for the one I bought from them I should still be able to use it? When I contacted them the person on the phone said I could use either phone and it would work. The lady today told me I could as well and then told me something different and then changes her story again. I just want to be able to have a phone that works and that's the one i purchased. If there not going to let me use my Samsung then please unlock it so I can give it to someone that can use it. Also A phone that works would be nice. This new one is slower than a snail and I haven't even put any apps on it yet.
