Capital One Credit Card Complaint

Capital One Credit card department,

Other fee California

Hello, I am submitting this complaint against Captial One due to non-compliance with a complaint regarding billing. On -/-/15, there was an autopay to Capital one from my Bank - account, which I did n't authorize. I went online and changed my due dates for automatic payment, which the indication that this change would take place promptly. When I attempted to contacted Capital one, after the money posted to my credit card account. I was informed that if I Changed my due date, it would would take up to - billing cycles. I then talked to a manager and informed him that I was never informed about the process of the billing cycle and that this was the second time that I changed my billing date and Captial still charged my account. The funds were n't returned and I was charged an extra fee by my bank. If someone could follow up with Captial one regarding this matter, that would be great!
