Avoid Samat Gallant as contractor

We used Samat as general contractor to do various upgrades to our house. In the beginning the workmanship and attitude was great and things were going to time. However, then he took on too many jobs at the same time and his work started slipping. He pulled his best people off our job and left the remaining 2 or 3 people completely unsupervised. This meant that the project was not completed to time scale, he started demanding we continue to pay at the agreed draw rate despite not finishing the tasks. In the end we asked him to leave but are now left with a retaining wall that started collapsing, shoddy plastered walls that are cracking, tiling that is completely un-level and numerous other incomplete and badly completed renovations. Please avoid!!
