Useless

Its been three months now that I have settled my account with Mobicred for the past 2 months I been calling them to update my credit status on the credit bureau cause it still shows I am arrears which is effecting my credit n credit score they keep telling me it's going to be done but nothing happens it seems like they are confused which dept is responsible for doing the update no body has a clue yet somebody from there did put the initial "in arrears" results on the credit bureau
