Nimble Group ****mers

Nimble Group seems to be ****mers and *******. They have been harassing me and registering adverse payment on my credit profile for debt that I no longer owe. Somehow they have bought over debt that I had with RCS. This debt has been settled and I have even provided Nimble with the paid up letter. They continue to update adverse information on my credit profile and calling me and sending emails. I am going to file a formal complaint with the Ombudsman but wanted to expose their thievery and lack of integrity here.
