Cancellation of Contract during lockdown.

I joined fight club during the 199 deal winter warmer for 3 months last year, to which I initially thought was only for the 3months, I was shocked when in the forth month they deducted 649, to which a contract was thrown at me that I agreed on on following the instagram links, to which I accepted as an oversight on my side, now beginning on March I received an sms updating me that I had 60days remaining and need to log a cancellation once 30days are remaining, I try to do that now and all of a sudden to cancel I need to pay over 3k, or cancel end of May. I'm so confused, I just want out of this contract. We are currently on lockdown and it feels as though they are trying to make the most of the situation.
