On XX/XX/XXXX I received a letter from XXXX XXXX of FMS Financial Solutions ( XXXX XXXX XXXX. XXXX XXXX, XXXX, MD XXXX, XXXX ) regarding a supposed early lease termination fee from XX/XX/XXXX. I can provide the details of my dispute if you need, but when I called XXXX XXXX he started yelling at me in a most belligerent manner, and threatened a lawsuit. His conduct was most unprofessional and overly aggressive. He was trying to collect for XXXX, ( XXXX XXXX XXXX XXXX. XXXX, MD XXXX, XXXX ).
