i've complain to apple for more than 1 month. and now i just received a phone call telling me that it is the hardware problem and i will be responsible for the cost of repair.
this make me really disappointed. they even suggest me to go to the service provider i blacklisted earlier (and which i already complain to apple earlier).
I got apple direct contact actually because i complain for the service provider earlier.
The service provider does;t seem to be professional at all. They are multi brand service provider. And the technician there told me that they actually do nothing, they just accept the unit and then ship to another country for further checks. And they require few weeks just for that(Not including repair).
somehow, whenever i mention that a lot of other people having the same problem, app cs insist that complain on the forum are not formal complain, and there are not a lot of this case.
Logically, if this is not the software upgrade issue ( or software upgrade causing hardware damage), there cant be these many people having the same problem at fairly the same time . Unless Apple also have hardware batch defect.
I really encourage people having the same wifi and gps problem after software upgrade to file a complain to apple. So apple have no more excuse saying that this is not a common problem.
Apple cs keep insist to have a phone call instead of reply me by email. Which is really weird, as if apple is hiding something.
