New York Sports Club [NYSC]

I agreed to a $280 payment for one month with the personal trainer Dan who was fired. and for the next month was promised 4 half hour sessions per month each week for only 150. In the contract it states after a payment of 280 for the first month I will pay 380 the next two month but Dan told me to disregard that. Dan lied to me about the agreement and I'm a brand new member and brand new to the personal training. I put many friends and family members into the club. This level of professionalism is unacceptable.
