BAD CUSTOMER SERVICE (SIM SWOP)

i have been using a number for close to 6years which i attached almost my everything meaning business ,personal and social. The number is my main business line i can only track the numbers which called me and the recharges done from my internet banking which i think is enough to prove that i own the number. i bought the number from MTN and ported it to cell c which i think was a biggest mistake. i have called several times , spoken to consultancies who told me that i can only be helped in store. i have been up and down Century city and Pinelands stores but they cant help me. i have the proof of address, my passport and an affidavit from the police station stating that i have been using the number for more than 5yrs and i would like to take full ownership. i have lost business and i am still losing business since this is the number on all my business websites , social media pages , business cards and even all my OTPs go to the same number. i have done a sim swop with telkom it was so easy and efficient. Its seems as if the people i am dealing with are ******** or they don't want to assist. whatelse can i do i have done all they have asked me to do and i have burnt enough gas going to Cell C stores looking for help. do we have to write down all numbers we call and also take notes each time we recharge ? come on i call thousands of people every month i cant remember my call log. isnt an affidavit, proof of address , id and me enough to do a sim swop? after all the business i gave cell c this is disgusting!!!!
