Lack customer service

The way I am so frustrated with cell c consultants, I called for a sim swop first time I spoke to a lady and I told her I am using Telkom SIM card for my colleague and airtime might finish she asked me questions and said I failed asked her to get someone to call me back and she disconnected, had to buy airtime and called again and spoke to Boleka that one is very inconsiderate and does not have customer service at all, he took my number and said he will put me on hold when I asked why he is putting me on hold he said it's procedure then I asked why the other lady didn't put me on hold he said he is just following procedure. I had also told him I am calling with airtime but he did not care at all and kept on asking same questions over and over again then he later said I failed authentication. I have had enough with cell c **** service all the time I have to go through hell when I lose my phone, I don't know if you guys are trying to get more money through us paying R140 for a SIM swop done instore. I can't be recharging people to call you and get this kindly of service. I am definitely moving my number and cancelling this contract because you clearly don't need me as a customer.
