Sim swop still not active after 4 days

I went to an MTN the Grove Mall in Pretoria for a sim swap on 26/08, as my cell was ******. Until today the sim still shows "no service". The call center and the branch says the sim swap was successful, but there seems to be a technical issue that has been referred to their IT for investigation. But await for a sim to active after is just unacceptable. In the mean time I'm stuck with service yet my debit order for my contact will still deduct without fail on the 01/09. MTN your service sucks. Cell C sim swap takes 4 hours for activation!!!!!
