Sim swap procedure not good service

I'm currently dealing with a sim swap problem...my phone got ****** in the car and a week ago and called to block my phone...so I got a new phone and sim recently and requested a sim swap and I couldn't remember the security question, I have that number for almost ten years now also using for business when I blocked my phone.I was told to go to the police and get an affidavit and copy of my ID which I did and emailed to mtn... I called in from 13 Aug2020 and I'm still waiting for a sim swap to be done...I was told by the call centre agents everyday that a sim swap is being processed but still nothing I think its unfair for them to lie to the customers and only to find out today that I need to send them in yet I was first told to email them I did to *** and she hasn’t responded I also sent follow up mails and no one responded and now I'm patiently waiting and my patience is wearing really thin...I think this is unacceptable and have been with mtn all my life but this recent service I got really sucked...my old number that I want back is ***I was told to email to *** I will see what happens...if anything comes of this an number to contact me on is *** OR ***
