Angry mtn client

Good day

I am a very angry client at this moment as I called in to Mtn call centre several times to have ma number sim swap as I lost my phone and I failed their security questions and I was told to send documents which was an affidavit and copy of my Id and I sent the documents as early as 9:14 on the 25th april 2018 and I was told that my number should be active within 24hrs and patiently waited for more than 37 hours and I called to my suprise the request was sent by an agent that i e-mailed my documents to bt the team leader did not approve the request and the request was still opened after 37 hours of waiting with my cellphone off. The request was sent by an agent at 12pm on the 25th which was 3 hours later after sending a confirmation email to an agent if the documents were received .All I need is my number back that's all or whatelse can I do for you guys to take me serious?
