Nightmare Service

I am having issues doing a sim swop of a number that I have used for more than 2 years, I ported from Vodacom to Cell C and have had great service until now, I tried to do sim swop online and was told that they can’t help me if I fail the security questions. I don’t remember the numbers of the people I called last I use the phone for business and call many people everyday, I recharge a lot and know when but can’t remember how much I recharged with. I was told to go to police station make an affidavit which I did went to cell c shop and was told the sim was rica’d on a passport, don’t know how this is possible I had to provide my ID and had to go to bank to get a bank statement before I could buy the original vodacom SIM card to have it RICA’d someone messed up and now I’m being told they can’t help me. The funny thing is I did a sim swop in October last year on the same number with no hassle. The people at Cell C doesn’t care that the number appears on my business cards, ads and branding which will cost a fortune if I don’t get the number back they don’t even listen or offer to get advice from a manager or team leader there is just no sense of customer service, they are just set in there way of this is what we do and can’t do anything more. I am at my wits end as I don’t know what else to do to get the number back. Somewhere in this organization someone must be able to assist or provide a guideline on how to proceed.
