I HAVE PAID AN OUTSTANDING AMOUNT OF R262.52 ON MY CELL C ACCOUNT WITH NUDEBT I WAS SENT A PAID UP LETTER AND WAS ADVISED TO CONTACT CELL C AS THEY ARE RESPONSIBLE FOR MAKING SURE MY DETAILS ARE SENT TO THE CREDIT BUREAUS TO HAVE IT UPDATED AND REMOVED FROM MY CREDIT PROFILE. I HAVE SENT EMAILS WANDITH THE PAID UP LETTER,PROOF OF PAYMEMT TEC AND HAVE JUST RECIEVED AUTOMATED RESPONSES. I HAVE EVEN WENT TO CELL C BRANCH GOLDEN ACRE CAPE TOWN REGARDING THIS AND I WAS ASSURED IF WILL BE TAKEN CARE OF AND THIS WAS IN JUNE! AND UP TO DATE THIS HAS NOT BEEN TAKEN CARE OF AND IS STILL SHOWING ON MY CREDIT REPORTS WITH THE BUREAUS!!! WHY IS IT SO DIFFICULT FOR CELL C JUST TO SEND MY INFORMATION TO THE CREDIT BUEAUS TO HAVE IT REMOVED??THIS IS AFFECTING MY CREDIT SCORE AND I AM HIGHLY ****ED OFF!!!YOU ARE QUICK TO SEND LETTER AND SMS REGARDING OUTSTANDING PAYMENTS BUT WHEN ITS PAID UP ITS A DAMN STRUGGLE TO HAVE ITUPDATED AND REMOVED.
