Worst Gym Ever!!

I have been struggling to cancel my membership since November when I have notice, they asked me for 3 months notice to cancel I gave the notice in November, nobody has responded to my mails ever since and I am refusing to pay until such a time where I get a response to my mails that I have been sending, this is the worst GYM company in boksburg East Rand Mall ever I should have never signed up with them!! Their admin1 email address they gave me is not working and nobody is bothered to respond, Maureen is constantly sending me payment emails but she is not even trying to help with getting my cancellation sorted.
