Inconsistent with Intent

Yesterday I went to Cell C in Vincent park in East London to do a sim swap as my sim card is damaged. I asked the lady behind the counter to assist me and she abruptly said that it would cost me R114 to do a sim swap. I said to her my sim card is damaged, not lost or ******. She said that it would still cost me R114 this was after she told me on Saturday that I am not able to do an upgrade on my contract. After she told me this on Sunday I walked into Telkom Mobile and took out a new contract and I will be cancelling my contract with Cell C. I called Cell C today and they said a sim swap does not cost R114 its costs R50 which will be billed to my account. I am also trying to call Cell C in Vincent Park to query why they are inconsistent with their customer care, but their line is constantly on voicemail. Her inconsistency with their customer care was intentional as I feel that she did not want to assist me both with my upgrade and with my sim swap.
