beware of ********** - Nimble Group/ Nimble Collection Services

This Nimble Collection Services is nonsense. They keep bringing up an account that was closed over a year ago. Why are you still attaching yourselves to my credit profile when I have sent you multiple times letters that show the account was fully paid and closed from the credit provider. This is nonsense. This is just *****, you are trying to collect money from me that I don't owe anyone? I don't understand why you keep doing this when this was struck off from the bureau more than twice.
