Capital One Credit Card Complaint

Capital One Credit card department,

Customer service / Customer relations Washington

I have a business credit card with Capital One. Over the last several months, Capital One has ( according to their customer service and fraud departments ) changed my BUSINESS mailing address on the account to my residence address without my knowledge or authorization. I have just spent over - minutes on the phone trying to resolve this, only to discover they have changed the address yet again. They have escalated this to a " fraud '' investigation, yet THEY are changing the address - they say - based on information they are receiving from the Post Office. They have never verified these changes with me, the card holder. They simply change the address, and as a result the due date on the account also changes ( which is what prompted the call by me ). It seems address changes should be verified by the account holder, as anyone with computer access can put through an address change - and in this case - redirect mail away from the business address to a residence. Fortunately, it went to my personal residence, but these changes should not be made " automatically '' ( their word ) without verifying the change with the person RESPONSIBLE for the account. My attempts to resolve this through their customer service department was fruitless and incredibly frustrating, especially given the language barrier.
