EXPERIAN SA CUSTOMER SERVICE IS APPALLING!

I have sent emails which has been attended to by Mawusakhe Nkowane, Malungelo Piet and Lusizo Mati who have all been unhelpful. I want to dispute 2 accounts which I paid in September but one person responds today and tomorrow someone else requires the very same details you've already sent. It's exhausting as I have work to do apart from sending the same info back and forth to Experian SA advisors. The service is just appalling!!!
