Still Waiting

Well, I still have not received my phone back from my parents. We have a phone contract and part of it said I had to have at least "C"s in every class. For a couple weeks I had a "D" which I just brought back up to a "C". When I asked for my stuff back(phone and PSP), my stepmom said that I could get it back when they got my quarter grades................Well guess what????That's not on the damn contract........................It says when I have "C"s I can have my stuff, not quarter grades!!!!!!!!!!!!!!!!!!!If their not going to abide by the contract, neither will I..............
