Seller agent ignored appraiser report

[Nancy Fortenberry]

We were almost closed on a house when we got the appraisal report. The square footage of the house was off over 300 sq, ft. The selling agent ignored the report and would not discuss anything with us. Instead, he just said we defaulted on closing and kept our $1,000.  He knew we were buying the house for investment purposes.  The house was advertised as 3,050 sq. Ft., when in actuality it was only 2,745 sq.ft.   This made a huge difference in resale value, so we wanted a reduction in purchase price. He said we were just trying to rip the owners off! Really? We didn't measure the property, the accessor did. The report was correct and the selling agent put it back on the market at the wrong measurement. If we had gone through the purchase, we'd have lost a lot of money.  I'm so PO'd right now.  This agent is a jerk. Is there anything we can do?

Thanks for any insight on this matter.
