Looking for private flying lessons in Thailand

Hi guys. I'm looking for a decent school to attend a private pilot class, mostly for Cessna. I am quite familiar with the basics due to my experience in my home country's army but I never had the chance to pilot one. I'm here using a Thailand Elite visa so I don't have to worry about visa hassles for that - I'm basically looking for a place as close to Bangkok as possible to learn and acquire the licence. I've checked a few websites and the prices are pretty reasonable. I've already contacted a few companies:

1) thaiflyingclub.com - Sent an e-mail a month ago, it got graciously ignored. The phone got answered by someone with obviously limited mental capabilities who hung up up.

2) sravia.co.th - Sent an e-mail 3 weeks ago, it vanished in a black hole and nobody picks up the phone

Either Thai or English is fine. Does anyone have experience with that?
