Meritage Homes Complaint against Meritage Homes Irving, Texas

I recently bought a Meritage home at the Deerfield North community in Plano, Texas. Meritage Homes claimed in their advertisement and flyer that the house has square footage of 3452 . However the appraisal report shows that the house's square footage is actually 3332 only. The difference is 120 sqft. This is not a small number and is big  enough to accomodate another bedroom. In terms of dollar amount, I have basically lost more than $10000. Also from Meritage Homes document, I found that they misrepresented the square footage by adding at least 86 sqft of the house garage extension into the living square footage.

I have requested their DFW Director of Sales to compensate my loss of over $10000 due to the loss of square footage. But he denied it and blamed that it was the appraiser's mistake. Then I requested Meritage Homes to re-appraise the house, he refused to do it. Rather he warned me that if I choose not to close my home purchase transaction, they would take away my earnest money (which is more than $20000) and sell the house to other people.

It's hard for me to believe Meritage Homes as a public company has such poor customer service with focus on customer's money rather than customer's satisfaction. It is the most unpleasant experience to me as a customer.
