ah shoot..my iphone 7 camera got problem. Fromt camera is working, back camera got blank and flash not working. Restart & updated firmware not solving it. Bought with umobile, where should I sent it to?

Phewww...finally got my iphone 7 iSight camera fixed at QCD at Times Square..5 stars for the services. Managed to get it fixed in 2 hours. Somehow nothing was wrong with the iSight camera but after it was opened, the guy saw that the camera flex cable ribbon was 'tercabut' from the motherboard..weird that could happened, probably due to manufacturing issue. 1 star for Machines KLCC @3rd Floor though for my prior trip to QCD, doesn't even bother to perform proper Analytics..doesn't even bother to check if I got any warranty left..just spew that they can receive my unit today but will have to wait until a week after raya to get it fixed. Claimed that the service centre where they will send my phone (in PJ) will close for Raya, 1 week before raya and open back 1 week after raya..that's not including waiting period for parts ordering..My feeling is that they probably had too much faulty units on their hand right now and tried to push away customer..
