Useless customer service

Been trying to get in contact with customer service. I signed up for a 12 month membership, or SO I THOUGHT! Myself and my husband asked for a 12 month contract, the sales assistant assured us it was 12 months. Fast forward, I want to pause my account as I am about to give birth and won't be using the gym, I go to read the contract about pausing, there I notice its 24 MONTHS! I email them, but they just ignored my query regarding my contract time span. I've been trying to pause my account still to this day, for 3 months now!! And they are wanting me to give a doctor's letter for being pregnant!?

They are very quick to deduct money, but can't reply to emails or anything. Honestly soo USELESS!
