Client ******* into joining the membership

I am not happy with the way i was ******* into joining virgin active membership.the consultant Steve aproached me at mall of the North to tell me about the 2month promo they were having at virgin active for 100.i was not given a chance to read the terms of reference he told me to just sign.i thought i was signing for the 2month promo they had,he said everything will be explained properly when i come to the gym.i paid the 100 upfront.i hv never set foot at their gym.i was surprised when an amount of 250 was also deducted from my account.i went to enquire at the branch and spoke to the manager Munisi.i explained about the misunderstanding but Munisi said unfortunately i am already a member.i asked how can i cancel and i was told i can only cancel when i pay a 20%of the outstanding amount of 24 months.i requested for the terms of the contract and i was told it was sent to me on my email.at that time i did not have data to check.i have checked all the emails and they hv not sent me any contract.i feel ******* and mislead by Virgin active..im disapointed in the way they operate.
