Mtn Canal walk Disgusting service

MTN canal walk. I upgraded my phone to iPhone pro max 16 in June. Used the phone for 10 days and it stopped working/charging. Took it back and was told I has to wait 14 days to get it back. After 14 days there was a warranty claim and I got a new phone. Same thing happened with the new phone I received so clearly an issue but I was told I need tio wait another 14 days. This time the warranty happened quickly, however, I am told there is no more stock on this device so now I have to wait for the iphone 17 to be launched and I have to Pay in! There is nothing else to be done. So I have paid for 2 month on this contract and had a phone for 1 month. Im expected to continue paying for my contract without the phone. Let's not get started on MTN not giving ANY paperwork on these unless I threaten them. The manager who tells me he doesn't work on the system so cant help but after my 9th visit to the store he finally gets off his bum to assist and miraculously can now work on the system. So here I am, phoneless, out of pocket, no resolution in site. The complaints department responds to emails every 3 days and gives non chalant responses. No results. We have 5 contracts with MTN and once finished will NEVER use them again. Disgusting service yet if I dont pay for a phone I dont have they will blacklist me
