Citibank Debt Collection Complaint

Citibank Debt collection department,

Credit card Improper contact or sharing of info Contacted employer after asked not to Massachusetts

I contacted the collector and made arrangements to pay the debt he contact my work repeatedly, in the same hour. Then proceeded to contact people i havent spoken to in years on my - account asking them to contact me and tell me to be home because im going to be served papers to go to court. All in less than - hours of making payment arrangements.. that I called to make! this is harassing and embarrassing.
