I bought my 6s Plus last November 2015. I had it replaced 3 times already due to various issues with the screen. July 2016 - uneven backlight in the lower middle portion of the screen - replaced via QCD October 2016 - upper left corner of the screen is dark, maybe backlight issue again - replaced via BTB November 2016 - upper left corner of the screen issue again - had it replaced via BTB. December 16 - When I went to BTB to get he replacement, it has a dark dot and spot on the upper portion of the screen. The BTB's staff said that it is normal which I did not believe. So I did not accept the unit. I asked them how long will it take to get another replacement and they said that it will take another 3-4 weeks (after waiting 3 weeeks) What I did after that was to call Apple Support to raise my concern about their replacements having defects. I was transferred to a senior service advisor. He said that he will try to have my unit be replaced by a brand new one since I had mine replaced three times already. It took him almost a week to had my request processed. He even called BTB to had the replacement phone diagnosed and it was confirmed that it is really defective as I suspected. December 28 - Since the senior advisor will be on a long holiday leave, he transferred my case to another one. The new senior advisor advised that I get the defective replacement unit from BTB which I did. He then tried to file request then he advised me that there was a system issue on their side so the replacement. He asked me if I can wait up to next week. I accepted since I can use the defective replacement phone for the meantime and I guess January 4 - I decided to make a follow-up. The senior advisor tried to file the request again but it did not push thru again. He said if it is ok if I wait a week again and he will follow-up with the engineers the system issue that he is encountering. I am already pissed but I said ok he can call me again next week, January 11. What should I do next? I know it will take a bit longer since it is the holidays but I did not expect that it will take 4 weeks for my request to be processed. I will be getting a brand new phone which is good but the wait is too long. What do you guys usually do?
