I did loan finance and signed all documents then I started some online research. This site popped up to show that I might have done something I should not have. I then signed the form to stop the loan before it was funded. They funded the loan anyway on the second day after signing. Cross Country received the paper next morning by overnight USPS. I should have had 3 full days. They are saying that the paper was never received, I have signed receipt showing received by them on the 2nd day after mailing. What should I do?
