Citibank Credit Card Complaint

Citibank Credit card department,

Privacy Illinois

I presently have a credit card with Best Buy ( Citibank is now the lender for this card ). I am presently late with my payment due to a change of salary from my primary employment ( which is struggling ). The issue I encountered with the bank is this morning they contacted my parents home asking to speak to me regarding my credit card. My mom who just was released from the hospital after a month took the call. First of all I do not live at my parents home. My application DOES NOT have my parents number listed as a contact. I do know how they obtained this number. I have been a customer of Citibank for approximately 18 years - holding several checking accounts with them. This branch went into my personal banking files where I know I listed my parents as a reference. I understand a credit division has the right to contact me in this instance, but I DO NOT feel they have the right to fish '' into my personal banking information and obtain a family members number. Is n't this against the Fair Debt Collection Practices Act? I would appreciate any investigation into this matter. Thank you.
