Good point. I will call them tomorrow.
By the way -- and I am NOT saying this to be critical -- it is a good idea to study the policies and practices of each of your creditors or potential creditors. It can not only save you time and aggravation in the future, but quite possibly save you from a wasted hard inquiry.
Yes...I'm very grateful they gave me the opportunity to decide!
A lender can give you however much money they want and is under no legal obligation to keep the credit line they give you. I'm not even sure why that's a question.
