Citibank Credit Card Complaint

Citibank Credit card department,

Michigan

I did not receive the last bill for purchases made at Macy 's. I received the next bill which included interest and a late charge which is due on -/-/- 2017. Everyday since I received the second bill, I have received a robo call from them. I responded to the call and let them know that I directed my bank to have an automatic bill payment for the full amount within the week. I still continue to get these calls. I have excellent credit and have never had this kind of treatment from any creditor. This is unacceptable.
