Deactivate my account urgently

I submitted dispute with all four credit bureau companies and provided a prescribed letter to confirm account has been closed ,3 company has closed that account due to insufficient information from the bank , Experian re open the account while letter of prescribed has been provided

Claiming new evidence has been provided.

How do the bank provide them with evidence whereas they are the ones who provided me with prescribed letter

How do I de activate my Experian profile urgently?
