Gym Company blacklisting threats!

So they cornered me to join the gym in Westgate Mall. I told them I live in Rustenburg and the guy who registered me confirmed to me that indeed Gym Company has a branch in Rustenburg. I get to Rustenburg one week later, searched for GC, lo and behold, not a single GC branch to be found. Now they call me to threaten me with blacklisting. They won't see a penny from me, like I didn't see any GC branch in Rustenburg

User's recommendation: Don't sign with Gym Company.
