Planet Fitness Northmead Benoni is *******ly signing in people

Planet fitness is absolutely pathetic. I neva signed the contract but they allowed som1else sign on my name I tried for 4 months now to cancel the contract. With no call from manager sales person or call centre. This is *******. Now i get a call sayin I owe money But I neva signed and asap went to cancel. 3 months later I get a call asking for money owing wot nonsense. Very unprofessional.
