Wrong profile update and disfunctioning call centre

I has an account with MBD attorneys, that was settled on the 6th of february, MBD has sent Experian the instruction to update my profile to paid in full, instead Experian hac updated my profile with an error of me owing MBD R129, i then took it up with MBD, Johanna was so helpful and sent me the copy of the sent instructions to Experain, when i call experian, no answer at the call centre, when i call reception, the lady transferes me but no one at their call centres is answering my call, this is been 3 week calling experian and havent spoken to a person to assist with my Query, this is really affecting my credit score and want this to be resolved as soon as possible, as the law say the update has to be updated 7 to 14 days after payment, i am on the 19th day and no one is answering my call not even the emails MBD sent, i also sent emails no respond.
