Pool for Aqua Aerobics

I have been a member of LA Fitness for at least 4 years.  The pool was closed down  several months ago so the water heater could be replaced ( or so we were told).  Now the water is freezing cold and we're still being told that it's the water heater!  The people at the front desk don't seem to care and our Aqua Aerobics classes are getting smaller due to the freezing cold water.  It's a real shame because the instructors are excellent . .  This problem needs to finally be fixed!
