Number change

Requested a number change last week Tuesday, I was told it would get activated with 48hrs however it's still not resolved and each time I contact the call centre I'm told different stories, and some are saying doing a number is R250 and others are saying it's free. Money isn't an issue but it seems as though they've got consultants who are not customer oriented or product oriented. It's such a disgrace. Using mtn as well for work purposes and I've never experienced such poor service from them. Cell c is a shame
