Nimble Collection Services damaging names and bad service

I downloaded an app called clearscore just to find out that this Nimble Group has me owing funds of R 9 900.00, I have sent two inquiries to this Nimble Group to find out why this is showing, I don't owe anything on my two vehicles, I don't owe anything on a house, I am not placing my private information here. I would like someone to get back to me in this regard. I feel this company is making a lot of trouble for others , damaging reputation, and damaging credit worthiness. I seek that this amount be removed immediately from my name. You left me with no alternative but to place your company name here for all to see because you have not come back to me after two inquiries sent. This company has he worst service that I have come across.
