Sim swap & service delivery issues

Once again writing a bad review due to bad service from this company! Phone got ****** on Friday and had to do a swim swap, did sim swap at Benmore Sandton and waited 24h as instructed, nothing. Went to MTN Cresta and was told it did not go through so they re-did the swim swap process and was told to wait 2 hours, if nothing I need to switch the phone off for an hour and wait. Did as told, still nothing. It will probably take me another 4-5 visits to a store wasting my time and money just to get something as simple as a sim swap done and in the meanwhile I cannot access my banking accounts or my work accounts due to not having my number. This is the service MTN gives, but they charge an arm and a leg for data and service but when you need service delivery it is non-existent. I regret ever taking a contract with MTN and will surely be cancelling it pre-maturely to move over to a competent service provider that have systems where the BASICS work properly.
