SSDA is a ****, they pay my debt so that it remains listed even though its prescribed

I have a listing on my credit profile, it has been there for years, listed as Shapiro, last year I started to get some income and started to clean out my profile, there is a debt listed by this company which keeps rising in interest, it was around 4k now standing at 6k. I started to email them, they responded 2 months later, informing me they know nothing about this so called "debt" I should follow up with alefbetlearning or something like that, I followed this other company told me the debt is closed and they requested it to be removed from my profile this was in October last year, I waited in December decided to check my profile it is still there, contacted Experian they say I made payment in October literally a week after recieving a response from SDA and this other company and the account still gains interest, I honestly contacted them to make arrangement but if the account is closed who keeps paying for it to continue being listed as active and that is surely not me, isnt this an ******* practice to list it as being payed to avoid it being prescribed, I am taking this matter to NCR and Ombudmen, they cant continue doing this or is it a racial thing, they do ******* activities on my profile, I cant do nothing, I cant even get a easy credit card because of this listing that both parties have no clue and useless Experian tells me SSDA should sent a prescribed letter and instruvt them to have this removed, I need this sorted asap.
