DMC

I was handed over to DMC by Truworths last year. They phoned me we did make arrangements for monthly payment. All good and well they stop the deductions in 2024. Phoned there recovery department they told me that I'm not on there system they don't find anything of me. Phoned Truworths they say DMC Recovery must have on there system. All I need is a pay up letter because they still flag on my credit status. The DMC marketing department also told me that I need to talk to recovery.I don't know what to do. I need to clear that flag because it's affecting my credit score.
