How can we trust Apple Authorize Service Center quality?
I Just finished long discuss with Apple Support SG and known that, Apple have no agreement or NDA with their Authorize Service Center in Thailand and cannot control any quality or responsible (How this happen to apple and no warning to customer?). Seems If you accidentally bring apple products to all these service center, you have to bet with Luck. or Find an Official Apple Store in that country instead?
