Deceived by Body lab gym

Please do not fall for this so called gym. I was deceived by one of their consultants at Sammy marks in Pretoria. I don't know if they have been trained to lie to people because they all tell the same lie. They tell you to join the gym and promise you free access to the gym and thereafter they say you will decided whether you want to stay with the gym or not. I have never been to the gym but to my surprise the Body lab gym started demanding payment and threatening to blacklist me. I told them countless times that I do not have a contract with them but they insist that I do have one with them. I wrote them an email even called them but they did nothing to assist me and I was told that I will have to pay a cancellation fee after cancelling my "contract" with them. I told them I will never pay a cent and not knowing what on earth I'm paying for. If this is how this gym gets to get customers and ******ing money from them then it's really pathetic and sickening. A lot of people are victims of this so called gym especially students and at the end of the day it ruins their credit record all because of being deceived and duped by joining this gym. It shows that this gym is dishonest with their business and they are ******. I urge you guys do not sign up with this gym or agree to anything their consultants sell to you.
