i am tired since October last year fighting the same thing

i am writing for the second time seems like planet fitness is not being fair to their customers...i have been enquiring about my vitality membership that i signed with their employee and i even paid activation fee but no one is saying anything to i keep calling with no help still... was told i can cancel anytime time the membership now they saying i can not ... so i don't have access to gym for 6 months after signing yet i can not cancel my membership....sales guy from the gym says head office should assist and head office is saying gym sales person is responsible.... i am tired of wasting my airtime calling and nothing is said to me since October till now i am paying vitality for nothing all these months...
