Stinging disappointment DEXIM

I bought this case for Iphone4 + battery DEXIM end of June 2012, and after three weeks the fixed supply connector (female) on the case began to move and no longer makes contact so that random, after manipulations increasingly burdensome. By consulting the catalog Amazon I realize that the item is not already "more available" and I understand that I got screwed ...
This is all the more deplorable that for two years I was using without problems chargers and Battery + Case for Iphone3 of the same brand, which gave me any satisfaction (unfortunately the Iphone3 case is not recoverable for 4). I will try to last as long as possible this gadget which still cost me 42.90, and then I will refer his body to the sender - if I'm not too bummed.
Morality tristounette: another manufacturer Bouzille its brand.
