Disgusting service by MTN

I am due for a phone upgrade since April 2021 and have tried online as well as with two MTN offices without any success. Apparently MTN have a new system and my name is still on the old system because my ID number was linked to the Company where I was a Director about 11 years ago. If I want to do a upgrade I must therefore do it on the old system where the packages are different and more expensive as advertised by MTN. It seems as if no one cares to move me to the new system as I have already sent a email (from the Company involved to confirm that I have resigned as Director already 11 years ago) to MTN (Taufeeq Salie), as requested by him and it is now two months later and nothing happened in the meantime and he does not even return my emails. It does seem as if MTN has a monopoly and do not care about the image. Their response to hellopeter comments is also proof of that. Something need to be done to their attitude
