K. Hovnanian Homes review: Buying horror story and refund horror

I signed a contract with KHOV and they mentioned they match the appraisal price if the home doesnt appraise for the contracted amount. Contrary to that, only if you use their financing does that happen. In addition, I believe they are buying mortgages under their paper and depending on your credit from 630 using one bank and 640 using either Wells or BOA then moving your loan to one of those banks. Problem is, the houses arent worth the amounts. So I called the management from Va to Nj and they dont care. Then now waiting for more than 7 weeks on my $1000 refund after numberous emails and calls remain unreturned! Buyer beware, run from them! Oh and the house is now listed at 327K when it appraised for 283K and I offered 299K. Tell me crooks arent still among us?
