Consumer records not updated after exhausting the options available- Experian Credit Records

I have contacted *** to Dispute accounts with proof of paid up letters with no response since 08th January 2020. I then thought that maybe they open probably this week so I emailed another following up query receipt of my email, still no response to date.

I called Transunion with telephonic acknowledgement that all the accounts were paid up, got a report from Compuscan with acknowledgement that all the accounts were indeed paid up .Could you please investigate why a consumer needs to jump through all these hoops to clear paid up records ?

Hope to receive consumer assistance regarding this issue.

Thanks in advance
