BAD SERVICE

I have been to MTN shop in Hemingway's in East London and I was assisted by a lady called Londa as my line was not working on my cellphone. I was told to pay R8 922, which I did on the same day on the 28 August 2025. I was given an assurance that my phone will be working and since then it is not working and have been to the shop again after I knocked off on the same day. Today, I received an email from MTN that before my line is opened I need to pay another amount of R 3 129, which I am refusing to to do as I was in the shop and now after 4 days later, I am given another excuse to open the line. I have been with them for way more than 10 years and I think, it is time for me to look for alternative and better service than this. No one has called me for this challenge.
