I am seeing the same thing with mortgages! Get a client passed with a lender then they turn it down on application! Any excuse not to lend!
Have you approached your bank? They might be the best people to speak to, at the very least they will be able to give you a reason why they won't. Do not get lots of credit searches done as it then looks to lenders like you are applying for lots of credit that you won't be able afford to pay back.
