MTN has the worst customer service

I have had the worst experience with MTN insurance my device was ****** in December and it took weeks to hear back from them regarding my claim, with them never contacting me instead I had to call them daily, once the claim was approved they told them that I had to pay an excess of R300 and asked for my delivery address which I supp**** them with. Then a week later with still no word from them I called and they told me they couldn't replace my phone because they did not have a delivery address so I gave it to them again, two days later I called to find out what the status of my claim was they then informed me that my device was out of stock and gave me a list of devices to choose from, I did they told me I would have my phone in 3 - 5 working days 5 days later with still no word from them I called again and they told me that the reason I had not received a phone was because the phone I had was out of stock and once again I told them which phone I wanted and they said that I would get it within the week, a week later I called and each day I was promised my device, I called every day this week and was assured that I would receive my device today. Today I call and they tell me that they they didn't have a reference number so the phone had not been dispatched to the courier so I call again an hour later and they tell me that it has only now been given a reference number and they do not know when I will get my device, it has basically been two months of me fighting MTN for a new device and the worst thing is that it is a business line! I want nothing to do with MTN and if I could I would cancel the whole thing and move to a different network!
