Paid up but still reflecting on credit burea as in arrears 4 months later

My capfin loan was hand over to MBD and I paid it up on 07/09/2021. Both MBD and Capfin reflected on my credit report. After a long battle MBD update the credit bureaus that it's paid in full and settled. Capfin however is reflecting on al my credit reports (for the same account by the way) stating the account is still active and in arrears. I emailed Capfin on the 11/01/2022 they told me someone will contact me in 24hrs...it's the 19th and nobody has even attempted to contact me. I called your call center today..they told me to call MBD. I then told the agent it's not MBD it's Capfin. She then gave me a contact number for the legal department. ***...called the number..number doesn't exist.

Can somebody please assist me with this. This is affecting my credit score negatively and I need it to be updated asap
