very angry customer from Goodwood

We bought a house from this builder last year, the aftersale service is a nightmare. Call the office,send e-mails, most of the time didn't return the calls or respond the e-mails (hang up on people). Actually, most of the community has a backyard hydroseed problem and the builder don't want to fix the problem. The backyards are filled with 20 % of lawn and 80 % of weeds... Very deceived considering the cost of the houses.....
