Sun Communities review: loan payoff

Hello, we sold our home through the office on September 17th. It's now a month later and the loan has not been paid off. We have contacted the office several times and the response we got is "the main office handles that, but I'm told it'll be paid off sometime this month". Meanwhile our interest continues to accrue daily and an additional payment was drafted from our checking account. I work in a home loan department for a major financial institution and know this is completely unacceptable. Please ensure this loan is paid immediately.
