iF there was an escrow shortage, they can seek additional funds to mkae up for it. It should be easy to determine: have them send you the information they used (e.g. records of payments into and disbursements from escrow) and review it yourself: you should be able to verify if there was an shortfall and also how much additonal money will be required to get it back on track. If they can't prove this to your satisfaction, or refuse to send you the information, then they may be cheating you; you could file a lawsuit against to seek compensation and/or to force them to reduce the charge to an appropriaate level.
