Unless escrow did your proration calculations from an earlier date you should not be paying any additional on those items you mentioned.Was an earlier closing scheduled and then postponed?

As far a paying off your loans goes..all I can think of is that your lender(servicer) is is on the east coast and funds have to be acknowleged by a representative to complete the transaction. Perhaps that representative had already gone home. Maybe your escrow just dropped the ball. You might want to clarify and demand they pay any additional interest due, if that is the case.

There is definitely no grand profit scheme by your escrow company.
