MTN Poor/Worst Service Warrant assessment

I bought a phone on contract at MTN Festival Mall early July (LG Stylus 3) the phone developed a software problem and it was always freezing and i took it to MTN Repair Center in Midrand Job Card ALWIC ********** on the 29th of August 2017. The following day I received a call that I should get a replacement phone from the store where I bought the first one after receiving a COL number. I got the COL number after 3days and then I went to MTN Festival Mall on 02/09/2017 and I was told that they dont have stock and they dont know when they will get it I was very disturbed with that answer they then advised me to go to an MTN store not a franchise. I then went to MTN Rivonia to ask for my phone with the COL number and after waiting for long I was told we cant help you here, you have to go back to MTN Festival Mall and my argument was how can you send me back to shop that does not have stock and a date of when they will get my phone but I had no choice because at the end of it all I still did not get a phone and in frustration I called MTN 808 to find comfort and possible solution and was told the same thing by the consultant which frustrated me even more because at the end of the conversation I was asked is there anything I can help you with as if my problem was solved during the conversation. I then went back to Festival mall again and I spoke to the manager(Luke) and he said still there is nothing he can do mtn has not send us stock and we dont know when we will have stock. I then called MTN customer services and was told to call ********** and after holding for 27minutes was transfered to customer services 808 and i requested for the manager who then said you need to go back to the store where you bought the phone despite me explaining everything I had gone through. Even at the time of writing this I still dont have my phone and still dont know when i will ever receive a replacement. I know am just one customer and based on my experience I know nobody cares and people are just doing their job but this is the worst service i have ever received so far and at least show some respect to my money i am paying could you please deliver as you promise its now a month without my phone and my account is up to date. I know its not easy to tell a customer to find another service provider but all this has been pointing to that indirectly. YOUR SERVICE on this issue SUCKS.
