Dmc is collecting my prescripted account

I have a prescribed account dating back to 2020, and DMC refuses to provide me with a paid-up letter. Every time I request one, they send me a settlement discount offer instead. It is ******** to attempt to collect on a prescribed debt. I have sent numerous emails requesting assistance, but instead of addressing my concerns, they continue updating my credit profile as though it is a new account. I believe this conduct is unfair and potentially in contravention of the National Credit Act and credit bureau regulations. I request that DMC cease all collection activity on this prescribed account, correct any inaccurate information reported to the credit bureaus, and provide written confirmation that the matter has been resolved.
