Citibank Credit Card Complaint

Citibank Credit card department,

Customer service / Customer relations Illinois

I missed one payment, and Citibank has called me over 15 times in the past 3 days. I have spoken to them twice to explain that I had been out of work, and that I was expecting my 1st paycheck in the next couple of weeks. I have also requested three times to have them stop calling, but they have persisted.
