After 4 weeks, the new led cover suddenly stopped working again and I went back there to complain, but to my surprise, they refuse to change or give me back my money. this led cover which I purchased for R1409.00 on the 13th-10-2016 and same day, I also purchase my Samsung galaxy 7 edge for R13999.00</p>
