Cell C atroucious service.

On the 6th of June 2022, I changed my service supplier from FNB to Cell C. I was given a Cell C sim card and asked to wait 4 hours to have my number ported from FNB to Cell C. Unfortunately I lost that card and purchased a new one. (Did a sim swap). That card worked for getting my number ported. That is when the trouble began. I can receive and send calls and send messages, but I cannot receive messages. I cannot get in to the Cell C app as I have to have an OTP. Dah!! This started on the 8th of June and I was told by the service centre that I would have to wait 24 to 48 hours and it would be sorted. I have phoned every day since the 10th and told that "there is no feed back". It is now over 36 working hours and I still cannot receive text messages. This is un-expectable. The worst service imaginable. To go to another service provider will be to start all over again and i cannot imagine what Cell C will be like if I have to port my number again.
