NO CONTACT - ***** !

On 04/06 at about 16:30 I received a call informing me that there was an attempt to do a sim swap on my contract phone contract. this was obviously an attempt at ***** and I did not give any information. after this call I tried to contact MTN to make sure that my sim/contract is fine but I could not get hold of anyone. everything refers back to the so called "call centre" 135 number. I could not report ***** as there is no option, I could not speak to a person as there is not option. the security of my sim card seems not to be of any importance to MTN. I have eventually sent 2 urgent emails to customer case a ***** email adress. I have received automated replies with reference numbers but have not yet been contacted by MTN. Considering that this was serious and urgent and I clearly stated so in my email, I am confused as how any MTN clients can trust the security of their information! I am a MTN client for 20 years and I consider this insident as very serious as it impacts my security. I expect an urgent answer. Nicolise du Preez
