Bad Cell-C service

I tried to do a sim swop today 31/03/2021 just after 11:00 and got a Simphewe who asked me a hole range of security questions. He confirmed that i answered all questions correctly. When he needed to send me the OTP number, it did could not go through from Cell-C's side. I gave him my alternative number and he tried sending the OTP number twuch. It could not go through. I gave him my work colleagues number for the 3rd attempt and still it could not go through. Cell-c system them blocked me and i was told that i have to wait 24hours for there System to reset. I tried calling again, as i cannot use a contract service i pay for diligently and regularly each month, only to be told by Nkha that i am blocked and that neither he nor any manager can override their System. He also told me that i must have provided them with the wrong information, making it my fault the system blocked me swim swop attempt. What nonsense is this. I feel like closing this account and going to another institution. People, the customers service at Cell-C sucks. I tried to tell Nkha that it is not my fault and that i don't accept being punished for supplying the correct information. Nhka just wanted to get me off the line and eventually said good bey, while i was still stating my case. Really is this how Cell-C treats their Loyal customers? Then i don't want to be a customer anymore. And neither should anyone reading this message.
