No assistance for ITC

I have had the worst experiences with Cell C. I have been wanting an ITC for close to three months now. I called customer service to blacklist my phone since it has been ******. They did the security questions and claimed that they will send itc reference number through another number. I waited for the sms. I reached out after sometime and we repeated the process claiming they will send reference. We received it through email not sms. I went to the store with the reference thinking I will be given the ITC used to claim, the store lady said I should call because the ITC can be given by customer service. When I call them whilst I was in the store they claimed that they called on the 22 February 2025 but I didn't receive a call from them. This is very poor service from their side and I wish I had an alternative way to solve this. Wouldn't recommend.
