KARMA POOLS

Gutted pool and work has stopped no end in sight. It has been 3 months of back and forth with Jacques from Karma pools and still the work he was paid for has not been done. The numbers we have are either always on voicemail or he takes forever to respond and even then never shows. The pool has been emptied and stripped and that is as far as it has gone. How do we go about tracking this lovely specimen of a human down??
