Complaint Review: David and Jimmy Chung (Brisbane)

I booked a personal training session with David Chung (aka Yun Chung) and he advised his brother Jimmy Chung will do the training with me. I paid 20 sessions in advance at $100 per 2 hour session so I can get a 30% discount if I prepaid. Thats $2000! Once I paid he didnt reply and just disappeared. I have tried to contact him numerous times and went to his house and he always says his sick and cannot come out. I am really dissapointed. Please DO NOT do business with these 2 brothers. They are total scums! 

The private gym they run is at there home located:

13 dowling place, calamvale, BRISBANE
