Abysmal service from MTN Cresta

I started experiencing 'no-signal' issues with my iPhone in early November (2018) The phone was booked in for assessment and it was communicated to me that 'someone' would contact me within 10 working days. I returned to the store after 12 working days (after not having received a single phone call) to enquire about the status of my phone.

The consultant denied telling me that someone would contact me and proceeded to tell me that it was my responsibility to follow up. The consultant informed me that she would follow up with the service centre and that she personally would phone me later that day. I returned the next day and again the consultant denied that fact that she would call me. To cut a long story short, the phone (under warranty) was deemed beyond repair and was due to be replaced by the store. To date this has not happened and I have yet to receive ANY communication from the store.

Now at this stage I can write a book about the abysmal service I received from the store as it is now the 21st of January and I have yet to receive a status update from anybody. I have given up trying to go to the store - one empty promise after the next. I have tried (unsuccessfully) to escalate the matter to the regional manager (on more than one occasion) So now, exactly two months later... I still don't have my replacement phone - so I am paying for a device which I do not have in my possession, nor has ANYONE contacted me to inform me as to what is happening with the matter. Shocking service MTN - way to treat a loyal customer of more than 15 years...
