Premier Fitness scam, bad cheques, lies..etc. Mississauga, Ontario, Canada, Internet

On May 30th, 2011 I've subscribed to annual membership with Premier Fitness, Milton, paid the whole year in advance by Credit Card CAD$337.87. They've lied to me on numerous occasions (broken equipments, hot water in the showers...etc.). In January 2012, without warning, they closed the place. After a long waiting I was issued a Refund Cheq for the remainder amount CAD$77.19. On March 19th, 2012 my bank (HSBC) informed me that the cheq bounced and I was charged CAD$5.00. I tried calling and emailing until I got hold of their head office. I went and met with Paramvir Kaur (who won't give me her designation or phone number) who promised me a certified cheq in the mail for CAD$82.19. April is ending and no cheq arrived and Premier Fitness is not replying to my emails (their phones are disconnected).
