Core Group Service Centre - iPhone 6S Battery replacement - POOR SERVICE

I took my iPhone 6S in for a free battery replacement as per the Apple replacement program which is valid until December 2018. The phone was handed in at the Eastgate iStore who confirmed that there would be no charge as my phone serial # was one of the affected units. My unit was working 100% and was in use until I handed it in.

2 days later I receive a quote from the Core Group service centre stating that the battery would be replaced as per QP (Whatever that means) however I would need to pay R2,999.00 for a screen replacement to sort out an audio issue identified by their diagnostics! By the way, there was no issue with the phone audio as the only problem experienced was the occasional unexpected shutdown which was supposed to be resolved with a battery replacement! I have tried in vain since 09H00 this morning to speak to someone regarding the quote and needless to say I have gotten absolutely nowhere! I just finished a chat session via the iStore website and I am none the wiser and still where I was at 09H00 this morning.

Apple international needs to address the poor service being offered in South Africa!

I think I am wasting my time with writing this review as I notice that Core Group do not bother to respond to issues raised on this site. Once again the consumer gets the brunt of POOR service.
