Debt Review account not found

I had an account with Finchoice and then had some financial issues my account was then handed over to Nimble and i was then under debt review of which i was removed from Debt Review in April 2024. I paid my account with Consumer Friend but since my account is removed from Debt Review they no longer have my account and I paid them December and January but they refund my money as they cannot take money that doesn't belong to them. I contacted Finchoice of which I can never get through to speak to an operator I then emailed them and was told to Contact Nimble when contacting Nimble they advised my account not with them and that I should contact ITC and they can check and see with who my account is ITC then said to contact Finchoice since I originally had an account with them however no luck I have been calling Finchoice days on end to no luck and also sent an email. I don't know what to do or who to call as no one seems to know where my account is and now this is impacting my credit score negatively as if I am not paying but that is exactly what I want to do. My credit profile really change towards a positive financial report and now this. I just want to know who has my account in order to make arrangements and pay the account as I want my credit profile changed. I honestly feel this is unfair on my credit score as no one is assisting me with my account information. What do i do or who do i call.
