Credit bureau incorrect info from Capfin

I had an account with Capfin that was paid up in 2017 through debt review process. I have been calling few times, and directed to a lady by the name of Raheela, to update my details on the bureau , and I have sent all the details they have requested including the paidup letter. Getting hold of this Raheela is problamatic, she does not answer her phone,or she is a meeting, or she left for the day. Please assist in updating my details a the incorrect info is a stumbling block.
