Not updating ITC

I have tried for days since the 30th August 2019 to get three accounts I have with finchoice updated with ITC all old closed accounts since 2017, to date I have only managed to get three Credit reference agencies (CRA's) updated, with alot of calls been ,made back and forth to Finchoice and the CRA's. it was the most daunting experience ever. Now I have one CRA left to update which is compuscan, I called compuscan and they have advised that they did receive the instruction to close accounts however this was not clear instructions. They have responded to finchoice asking for further details but no response. I called Finchoice and asked them to check up on this, yet they ask me to go back to the CRA and find out which email address they have responded to. I called Compuscan back and the consultant questioned why they would ask me to do such a thing as all they need to do is check for responses on my account from Compuscan. This is becoming so frustating accounts that were paid up months ago, have not been updated. As a part of my consumer right Finchoice was supposed to be updating information with the CRA's one a month, clearly this has not happened. I am not in a position where I am looking for finance but these closed accounts are showing on my profile as opened and affecting my affordability and credit score. Finchoice have no idea what stress they are causing me, by making this so difficult. I keep getting through to so many people at the call centre, yesterday I was promised a call back from the Supervisor Maurice, who never called me back. He seems to be busy everytime I call. I cannot get any joy from this, all I want is my details to be updated with all four CRA, and right now Compuscan has not.
