MTN IS FAILING TO DO MY SIM SWAP FOR MORE THAN 2 WEEKS

I'm very frustrated and disappointed with this provider, i"m a victim of hijack and assault, my phones were ****** on the 22 August till today MTN is failing to replace my number i been trying to do sim swap since 22 August the incompetency is very high, i went 4 different MTN shops in Durban they have different answers and couldn't help me, their handle on twitter is so pathetic their reps keep asking same thing since last week, i have undergone various MTN DEPARTMENT NO HELP, contract, prepaid and Business, i'm told my sim is business next day its prepaid following day its contract and sometimes it belongs to UNISA, its been 2 weeks i don't have this line and its my priority line i had it for more than a decade now and im not sure if i will ever get assistance i just lost hope i have 7 references that i'm given daily.
