Offered migration but status never changed

On the 26th of November i was called an offered a migration on my contract (after i struggled with trying to migrate a few months before because clearly the service offered is poor and your people in woodmead were not sure how to do a migration and they told me i could not have two contracts running, clearly they don't know the meaning of a migration ), the migration was supposed to be 20 gig day and 20 gig night for R199 which i agreed to and i was supposed to receive an email confirming the new terms of my contract, obviously the email never came so i called MTN for assistance ( they should have evidence right because calls are recorded right ? ). I called to check why i had not received any information and it turns out my status has not changed so a query was logged and a few days later i got text that the query had been resolved but again no information was provided to me so i called again this time another query was logged, It's been almost a week now and no one has even attempted to help me, every time i call the call centre all i get is " we have sent a request and someone from the migration team will call you", clearly i am gonna be 70 by the time i receive that call. I even sent an email which no one bothered to reply to. Do better MTN because the way you treat customers is shameful
