Very Poor Customer Experience - Epic Fail

Last week I called Cell C customer care 140 3 times to unlock and reset my self service PIN/Password. first attempt the agent told me it was done, after terminating the call I tested it, only to find out it did not work. Second call the Agent told me I could not register a new PIN on the same day, so I would have to call back the following day. I voiced my disgust that I would in fact have to call them 3 times to resolve 1 issue. 2 days later I plucked up the courage to call the call center for the third time. This time the agent could not assist, but did log a call for the technical persons to unlock my self service portal and they would definitely call me back , only call i received a Ref for ***. now 3 days later still no call. I refuse to call a fourth time for such a simple query. I have been a loyal Cell C customer for about 14 years. This certainly gives reason to change networks. since I cannot log into the portal it is a guess, but I have only 6 months till I can port my number.
