Morequity and Wilmington Finance

I accepted an offer from Wilmington Finance through Lending Tree. I specifically advised the loan officer at Wilmington that I wanted to be able to set up semi-monthly automatic payments. He said any company should be able to do it and it won't be a problem. Well, he was wrong, especially with Morequity. They won't even apply partial payments sent in semi-monthly as an "early" payment to reduce interest charges. In fact, I was told it may cause problems with posting. I followed-up with Morequity several times and still they won't take semi-monthly automatic payments.
