I had the appointment scheduled this morning with Santa Clara SC. I got this message last evening.
"Michael here from Santa clara service center, isee that we have an appointment tomorrow to address the yellow border screen concern, sorry to inform you but our tool was damaged and we can not addressed your concern tomorrow. we will have to reschedule you out till next month hopefully we will have the tool fixed by then if the appointment does not work for you please feel free to edit the appointment from your mobile application. thanks have a great rest of the evening!"
A friend of mine had the appointment today as well, but he got a message last Saturday saying the tool is not available. SFO South bay SCs are total crap, they open their mouth only to tell lies.
I went to Sunnyvale Service Center last week and they told me there is no fix available for Yellow border issue. When I asked about the UV fix they claimed ignorance.
