MTN still hasn't activated a sim migrated to prepaid

The service from MTN has now gone to being **********!!! When you have a customer service quality analyst call you to sort out the problem yet does nothing. I was called on Friday and told that the number has been activated and that a sim swap has to take place, after calling the call centre as I haven't been provided with feedback I have now discovered that this number has still not been activated. May I add that this is my husband's business line that has been inactive for more than a month now. *********** to the max!!
