Battery broken - print off - no guarantee

The fact that the inscription "Gigaset" has disappeared on the device by attrition after only 2 months, I consider now times as unhappy wear. We are not frequent users for all their love!
What really annoys us but after only 7 months of battery was completely over. He could not be more than 1/3 of charge and was after 10 minutes phoning all completely. Unfortunately Gigaset granted to the housing and the battery only 6 months warranty! Thus, in principle, everything is covered by the warranty, up to software errors. Really not worth the money insolence and for this price!
