Dissapointed with the service and sim swap process

On monday the 6th of May 2024 my mobile phone was ******. As a result i had to buy a new phone and attempt to do s sim swap on MTN. i went and bought a new sim card and attempted a sim swap by dialing *135#. i received an error that said "Due to a technical error your request cannot be processed" i called the call center they told me my number appears offline and they cannot do a sim swap. i must call again after 2 hour as they will apply for a reconnection. I tried this several times over 7 days and up until today i have not received my number back. the number was linked to my banking App and i had done a lot of job applications with the number and till today i still have not received help and each time i call the call center they tell me they cannot help even when i visit the MTN shop they have failed to assist. It is very disappointing and as a long serving customer of MTN i am considering changing my embership permanently. the remedy number that was logged was 509097 with no ressolution
