I had ordered a new battery and also came very quickly. However, after a few days when the problems started. The battery indicator My phone always showed full charge, although the cell phone a few minutes later because the battery ran out (1st issue). The proposed problem solution had not been successful, which is why I wanted to return the battery. Unfortunately arrived at the mission with no invoice (2nd problem - but pretty quickly solved). I printed out over the link the invoice and sent the bill, the faulty battery and a description of the fault strike-box. A few days later I received my mail back the way I had sent. Only "denied accepting" the memo was also on the cover. Well! So much for service !!!! 3. Problem and the end of my tolerance !!! I have no idea why the adoption was denied. But I know that I throw away the battery now and try my luck with another provider.
