Sim swap still not done after a week

I am so disappointed in MTN. I have been trying to do a sin swap for the past 2 weeks now. First I tried via the *135# number in my mobile, then when I failed I called the call centre and they advised me that if I fail again I can go make an affidavit at the police station then take it to the Morningside branch and a sin swap will be done for me. I did so, I submitted my documents to the lady at counter 14 and still nothing has been done. This was last week Tuesday. It's Monday an I still dont havemy old number back. This is the worst service I e have ever recieved. Especially because that number is linked to alot of important things including my business contacts. Highly disappointed in MTN.
