Class 'A' Lawn & Landscape, Inc.

Class A Lawn performed sodding and reseeding on my lawn and charge $1500. They promished that 50-70% result will be there for late seeding. I gave $1500 just for 800 sq feet lawn and they reseeded on my lawn. They promished me that they will reseed if the grass will not come in summer. I called the company and talk to the President . He is charging me 600$ for reseeding where as he promished me last time that 50-70% grass will come beacuse he is using best product and fertilizer. I need my lawn to be reseeded again with the money I paid him before or refund 1/2 of the money.
