Nimble Group Harrasment.

My wife and I went under debt review since January 2020. Wonga was one of the creditors. In 2020-03-09 the wonga account was settled in full. Now three years late my wife gets threatening emails from this Nimble group stating that she still ows them money. The statement that they attached is password encripted and we do not have the password. These email has been forwarded to our debt counselor and she has been struggling for 4 months to get any responce out of the Nimble group. These guys ar ****s and are pulling down peoples credit score with the hopes that one will pay them this that is NOT owed to them.
