Unhappy with services from Cell C and customer care

On 23 April 2020, I had a problem with my hadset self. I made a call to the customer care since I am a cell C customer. The agent who helped me and who's name is known to me were more interested in my account, than to help me solve the problem I were stucked with. After about an half hour we ended the call, and I still were left with the problem. I then used a friends phone to call his service provider's customer care center, and the agents there didn't hesitate to assist me even though I'm not a customer of them. The problem was solved within 5 minutes. This made me reconsider about my next upgrade date with Cell C. And this wasn't the first time I experienced problems with the customer care centre of Cell C
