3 Week wait for number migration

MTN's service has been absolutely appalling. <br> In October, I was billed an extra R450 on my account for data. I queried why my bill was so high as I had not downloaded anything to justify this amount. I was told that a detailed investigation would be done and a report would be emailed to me after 7 working days. I confirmed my email address and waited. Nothing materialised, but the amount was debited from my account. After such poor service, I decided to cancel my contract, instead of renewing it. <br> I called to cancel the contract more than a month before the time, but requested to keep the number I.e. to migrate to prepaid. I did not receive confirmation so called again a week later, to be told that the cancellation department would get back to me. Again, I heard nothing. Eventually, on the 10 Dec, I went to the store and the assistant informed me that the request had been captured incorrectly and the number was in fact going to be cancelled. I called MTN that day and was told to wait 5 days to be connected to the network. It has been 3 weeks, 5 reference numbers later and I'm still waiting. I've been a loyal MTN customer for 10 yrs,but I wonder if I should even bother with prepaid
