*********** and disgusting service

I settled my account with Norman in July, I called Wonga that my account has been settled yet it is still reflecting on my credit report as account in arrears, that was in August, they said they will update this in the credit bureaus and that it will take up to 31 working days, September I called them and informed them that my account is still showing arrears and the consultant said she has escalated it and it will take up to 31 working days once again because it was never done in August. Last week I call again that my Wonga account is still reflecting in arrears and is seriously affecting my credit score badly and guess what? I was told exactly the same thing I was told twice, I will be reporting this to the NCR as well as the relevant ombudsman, this is unacceptable, you cannot update now at the credit bureaus yet you are so quick to blacklist people?
