CELL C IS A DISGRACE WHEN IT COMES TO DOING SIM SWAPS

I am totally disgusted with Cell C at this very moment. I lost my Cellphone which had a prepaid number on the 27/10/2020. who in this time and age with all the cares and stress of life can remember things that happened even a day ago, yet Cell C demands you to remember things. I called in to do a sim swap and get asked questions that even a computer memory will have difficulty answering with all the hacking and viruses that affect the computers now a days. so how can a human being remember things that is stored on a phone that is NOW LOST. it is not like we write everything down in a diary for every transaction or call or sms or even worse, if you load 3 Vouchers, WHICH VOUCHER YOU ENTERED FIRST OR LAST, WHO THE F IS GOING TO REMEMBER THAT WHEN YOU DONT HAVE THE PHONE TO VERIFY. THEN THEY ASK YOU WHICH NUMBER YOU DIALLED LAST. ARE THEYMAD TO EVEN ASK THAT, WHEN YOUR PHONE WAS ****** AND YOU USED IT MAINLY FOR WHATSAPP AND MADE CALLS RARELY. THEN THEY GET EVEN MORE RIDICULOUS TO ASK HOW MUCH DATA AND AIRTIME IS ON THE PHONE THAT IS LOST. REALLY NOW IS CELL C GETTING MORE INSANE IN THEIR MEMBRANE AS TECHNOLOGY IS EVOLVING. PLEASE CAN SOMEONE PLEASE TELL ME HOW CAN I MAINTAIN MY SANITY WITH CELL C.
