Worst ever service!
Never trust them, they can keep your devices for a while, ask for a great sum of $$$ to repair, refusing would result in a mismatched device, maybe you could lose the original body of your phone, maybe you could end up with a dead battery and the possibilities are unlimited. I had just faced some of them while only refused to get their services, since the price quote wasn't suits me.
Anyhow, let others be safe from looting!
