Capital One Credit Card Complaint

Capital One Credit card department,

Billing statement California

I have a Capital One Credit Card and when I make a payment I notice that the money is taken from my checking account immediately. I made this payment on the on -/-/2015 and my checking account was debited for $400.00 on -/-/2015. I contected my bank and they stated the funds were paid on the -/-/2015. I checked my credit card account on -/-/2015 and Capital One still has not credited my account even tough they wree paid three days ago. This is the - time this have happened to me after I made a payment and payment was paid by my bank. I feel if they take a customer mone from their account knowing that its clear and hold it I should be paid. I contacted the credit card company via chat and they refused to release the hold stating it will be released on -/-/2015 even though they know the money is cleared. I think is is illegal for a company to hold an individuals money even though they have been paid and the funds cleared.
