Worse service EVER !!!!

Called customer service and it was the worse service EVER. Called in to reset my self service pin as I wanted to do my own SIM swap. Firstly I spoke to Akhona in the contracts dept which advised me that my number or SIM was blocked . Advised him that It's not possible a I lost my sim card few months back he said in order for him to assist me I have to wait 24 hours and can call back for them to assist me. However, he can transfer me to the SIM swap dept. Beeing transferred to the "SIM swap dept " was a complete nightmare, the consultant was rude,unhelpful and *********** and after i requested to speak to a senior he advised me that his team leader or senior was busy and put me on hold for almost 30 min. Eventually when he decided to take me off "hold " to "transfer me to his senior my call went directly to the voice prompt to rate the "service " which does not exist . I called back and got transfer from pillar to post and still no joy and NO SIM SWAP NOR WAS MY SELF SERVICE PIN RESET. I'm am bitterly DISAPPOINTED and DISGUSTED WITH the service at Cell C. !!!!!!After being with Cell C for almost 7 years I would not recommend anyone not even my dog for that matter to use cell c ......
