MTN customer care

My husband was ****** on 8 October. Sibce then we have been battling to get a sim swap activated. They keep telling us call backnin 5 days, then call back in 7 days. Then is is on, put phone off and check. Everytime it says account suspended. It is crazy that a company has NO-ONE higher than a call centre agent you can speak too. Will not ever recommend them to anyone.
