WORST SERVICE

I upgraded a phone contract for a phone I use for my mother. Came to visit her for Christmas and brought the new phone. Needed a sim swop, bought a new card, phoned in on the 23rd of December, apperently failed my security questions and was informed I can phone in 24hours. The following day I went to Cell C to ask them if I can do it instore. MatlosanqaMall Klerksdorp, I was informed I can only phone in 8 hours. Phoned the evening I was then informed the new sim was rica'd already. Phoned this morning 26th of December with a new Cell c sim, apperently I failed my security questions again,which is impossible. I asked to speak to a supervisor but no one available, they just walked in.. Will phone me back allegedly...I am on my way back to Cape Town and my mother stays 30km from the closest town. NO REPLY BACK YET FROM CELL C NO SURPRISE THERE
