Uns****ed Workers

i was approached by one of the sales personnel and told me about the gym and he said if i sign up i will get one month free then after he took my details and said that if i like the gym after the free month they will call me before they deduct money from my account, but they didn't even bother to call they just deduct my money without notifying me. This people they do not know how to conduct a business now they want me to pay for deceiving me they **** and tell me to pay. I WONT PAY THAT MONEY. i want out and what will happen if someone signs with them they loss their job, that means they will have to pay even if they can't. they should focus on people's healthy not destroying it .
