Experian is beyond incompentent

Experian has been an absolute nightmare to deal with, not to mention the surly agents who act like they are doing you a favour just for answering your calls. Telkom sent me an email on the 18th of December with a letter saying that I no longer owed them anything and therefore no longer under default, they further advised me that they had forwarded that letter to the credit bureaus and it would be updated within 7 days, of which Experian is the only one that has not bothered to updated their systems, it is now 14 business days later and I am getting my credit requests denied because of your incompetence. This is absolutely unacceptable.
