3 Months free Gym Membership not honored but used to lure unsuspecting customers to contract.

Planet fitness promised 3 free months when joining their gym yet they deduct within the first month going against their promise. I have been escalating this matter to no avail. It's tiring to deal with them with absolute 0 customer care.

I have been told my matter will be investigated every time I go there but nothing.I have asked to terminate the membership I was told I must serve 3 months notice which I agreed to yet I am blocked from accessing the club.
