EXPERIAN REFUSED TO REMOVE INCORRECT CREDIT DETAILS DESPITE THE PROOF

I have been contacting them for over a month now regarding false accounts on my credit report. There are two accounts from Wonga that I have settled long time ago still show up on my credit report (making it looking like I have over R10000 in loan repayments per month, when in reality its less than R2000). Despite me sending them my settlement letters and disputing these claims they refuse to answer my calls nor my emails. I literally CANT EVEN GET A LOAN OF R100 BECAUSE ON PAPER IT LOOKS LIKE I CANT AFFORD IT, DESPITE HAVING OVER R9000 IN EXCESS MONEY AFTER ALL PAYMENTS. FIX THIS! I literally cannot make necessary big financial loans (LIKE A CAR FOR WORK) because of this. THIS IS EXTREMELY UNPROFESSIONAL
