Trying to do a sim swap with Cell C is a nightmare

Went to Eastgate Cell C to do a sim swap as I was involved in a smash and grab incident. I was asked to complete 5 numbers on a form that I frequently dial. I cannot remember 5 numbers in my head, I could only remember 1. I was told that I should go home and ask my husband (I am single) to help me with the numbers. I was highly irate after having this number for over 7 years and in addition to producing my ID and having proof of address the customer care assistant was still insisting that I cannot be helped without producing those 5 numbers. Who rememorizes 5 numbers in this day and age. O asked the service assistant to give me a contact number for me to find out where in their policy is it stated that a customer needs 5 numbers as a condition for a sim swap. I was given a 084135 number to call bearing in mind this is a Cell C number that must be dialled from a cell phone having just lost my phone in a traumatic smash and grab incident. Why is Cell C wanting to know my 5 numbers when I have a right to my privacy according to the Popia Act.. They have enough information of me to assist. Needless to say, I will not be dealing with Cell C again because of the condescending attitude of your service assistant and the company putting barriers and roadblocks to doing business with them.
