Poor communication and service

I have only been with them for 3 months but I have had horrible experiences with them. In my first month, they deducted double the actual amount and then when I reverse the extra payment. They tell me I'm not allowed to enter the gym as I have not paid. The nerve, before I went to my local gym I call them I get someone who gives me an attitude and blames me for their mistake. I speak with someone at the gym and they explain to me that they took an advance payment, how do you do that without consulting us, your customers. I was then told that the month of march I will not pay but to my surprise, I see they took their money. Three months of hell.
