Where is management at MTN?

In June i had my phone ******, I immediately reported it, and the following day got a new SIM card and phone. In Sept/Oct my Gmail account was hacked again, I am sure its related to the phone theft, and i had to get new bank cards, change passwords etc. At the same time, someone did a self service purchase on my account. I DID not give out any passwords, or OTP at all. I have been trying to escalate this for 8 weeks, have repeatedly change balances back to 0, sent emails, sent affidavits, done everything asked of me and to date NOTHING has been done. NOTHING has been escalated, and its blamed on everyone working from home!!! I cannot get hold of management, or the ***** division, and everytime I call, I get an sms saying my query has been closed.

What do I need to do to get a response from MTN?

I have now been trying to escalate
