While searching for a mortgage lender to refinance for a lower rate I was quoted 3.75 APR with Quicken. When I politely confronted him with the need to have his quote in committed in writing before I make a deposit he became fast talking, rude, and hung up on me. I said nothing to provoke him. It was rude and unprofessional. It also made me suspicious that quotes were changed after deposits are made. This should be investigated.
