battery charger warranty service takes too long
I purchased a battery charger pack on Dec 1st, 2014 in companion with an iMac 27" Late 2013. The Keyboard and Magic Mouse worked great with the builtin batteries until March 2015. The problem was that the rechargeable battery capacity was always only 85% no matter how long it was plugged into the power. I took the battery charger and battery cells to Future World (premimum reseller in Vietnam) on Apr 24th, 2015. It is nearly one month that I have not heard any information about my case yet. I believe that such service is too terrible. Should I continue my endless waiting or do anything else?
iMac, OS X Yosemite (10.10.1)
