Barclays Credit Card Complaint

Barclays Credit card department,

Late fee California

My wife makes my payments for me online. She usually makes the payments the day they are due or the day before. She makes the payments online. I recently looked at my account and found that I was charged late fees even though the payments were made on the due date. I find it hard to believe that it is legal for a credit card company to take my money ( payment - out of my checking account on the due date and post it the following day in order to charge me a late fee. Is this legal? I want them to credit my account all of the late fees they have charged me in the past year.
