Horrific customer service from Apple and the Istore in Woodlands Pretoria

On 26 January 2021 I purchased a MacBook from the woodlands Istore in Pretoria, a few months down the line I began having continuous issues with the unit. it would freeze while I was working on It and display a purple screen to me, then restart and show me a page of code and a notification saying that the problem had been reported to Apple. As this issue persisted I then took my unit in to the istore, booked it in and the store technicians attempted to resolve the issue. a few days after booking it in, I went to pick it up and shortly after that, the same issue occurred. I then returned to the istore and explained that the same issue had occurred and they then told me the unit had to be booked in again and sent to the service centre. Having gone through this draining process I have lost all faith and trust for my Mac and I am convinced that I have been SOLD A FAULTY UNIT. My warranty ends on the 26th of January 2022 (in 2 days from writing this) and when this issue happens again it will be under my responsibility to pay for any services and repairs needed. I requested for a warranty extension and that request got denied. I then requested from the Istore in woodlands (PLACE OF PURCHASE) for a new unit and that request by no surprise got denied as well. instead I got told to contact Apple Support (which costed me a 45 minute call) that they would be able to help me in terms of receiving a new unit. After the long and tedious call, NOTHING got resolved and I got told to go back to the store that I purchased my unit from and that they would be able to help me. Simply put, I was being bounced between the two as neither of them wanted to help me. I am a big fan of all Apple products but I have been let down severely by the customer service that APPLE as a whole provide. As big and reputable Apple are, I honestly expected much more than I got after purchasing a product of theirs which cost me R18,000.00. I am extremely let down and disappointed, if I could give 0 stars I certainly would. If this issue is not resolved within due time I will be taking the issue further by contacting the media and blasting this story all over social media until the problem gets sorted.
