Help rescuing 3 cats - Patong Beach

I'm currently in Patong Beach until Wednesday and I found 3 cats earlier who need help. It looks like 2 adults and a kitten/young adult cat. They are living on a building site and one of them has a wound on it's neck. I have given them lots of food and they were ver hungry for it.

If someone could help me get them somewhere safe I would really appreciate it.
