Lying agents

I saw their add in Facebook saying membership from 299, i enquired because it was the closest gym to my work. A consultant contacted me and said the ad was for students... I told her I don't want to sign up as I already have a free gym membership at work, which was far so I wanted to save on transport. She then said to me there's a promotion for R320 if I sign up that month, i told her it's fine I came she told me to sign in her pad and I'll get the contract... I then called the call center to make an arrangement to pay the R1000 initiation fee and I was told there's no such thing.

I sent an email to cancel, they told me they can't cancel... Don't bother joining this gym. The agents lie to you. Now I'm being told I have to pay R799 a month.
