USAA Savings Credit Card Complaint

USAA Savings Credit card department,

Closing/Cancelling account Florida

I had an existing Master Card issued by USAA bank. Without any notice it was changed to a Visa card. They advised this was a " business decision ''. I currently have another visa card. I advised them I wished to close my account and was advised this could negatively impact my credit score by as much as - points. This is wrong for USAA bank to do this and worse that my credit score would be impacted by cancelling a duplicitous card.
