SIM SWAP ***** - GETTING NO HELP FROM BRANCH

MTN Maverick, Milnerton did a ******* sim swap on my Data account on the 16th April. I have been trying to get information out of this branch since Saturday 21st April. The staff member handle that did the sim swap is Swart_ju and the person who requested sim swap cell no is ********** (no one is answering number). I personally spoke to Juan Greef (2IC) at branch on the 23rd April. He said he has to wait for staff member to come in to investigate. He would phone back at 11h00. I then phoned at 11h30 and was told he is not available. I spoke to the branch manager Chad. He informed me he had no knowledge of my query. He said he is busy and will phone back. I advised him that we are not talking about someone steeling sweets but about SIM SWAP ***** and that I am unhappy that they do not treat this query with a matter of urgency. I requested copy of sim swap request as well as the ID copy of person who requested it. I have just phoned the branch again (the 24th April). Juan Greeff is not in today and Chad told me in no uncertain terms that he will phone me back as he is dealing with a client. He also said he is waiting for Head Office ... but could not say what is the uphold. This is absolutely terrible service that i am getting as a client, and a client who has experienced SIM SWAP *****. I phoned MTN customer service and they just as unfriendly. I need this matter resolved as i need to see the ID which was associated with the sim swap request as this can have HUGE repercussions for me personally
