Utterly useless and very poor service

Never do bussiness with Experian they are worse than Telkom which is utterly useless and very poor customer service. I have send them 3 emails 3 weeks ago too log a dispute they took 3 weeks to reply on my emails. There is a negative reflecting om my credit profile from Edgars an account which I settled more than 10 years ago, I told them to take it of my profile as I have not received any phonecalls in the past 10 years in regards of this account and that I dont have any invoices, settlement letters or what not, because I have moved 2 times in the past 10 years and the documents got lost or thrown away in the process and it was supposed to be closed long ago by Edgars, so Edgars did a **** job in the first place and because of their negligence has caused this problem. Experian didn't even read my emails properly if I look at their reply. They are utterly useless and hopeless.
