I had a very bad experience with MTN

I had a very bad experience with MTN. I am blacklisted because of mistakes on their side, and I have not been able to get this resolved since as far back as 2024. I have visited the store many times, sent numerous emails, and contacted different call centre departments, but the service has been extremely poor. At some stage, my calls were even disconnected multiple times while trying to get assistance. I have proof of all the emails and payments made. I am very disappointed with the level of service I received from MTN. I am blacklisted because of their mistakes, and I still cannot get this matter resolved. Can I please get assistance from the Ombudsman to help remove my name from all ITC platforms? This situation has affected me negatively, as I am unable to get a job because of this issue.
