Planet fitness in Bedfordview is just out here robbing people.

I am on a month-to-month contract, When I was unable to pay in November, they said I won't be able to use the facilities, So I got blocked from using the gym November and December, I have now paid January, they only allowed me for a week then blocked me and insisted I pay for November and December, how? when they refused me to gym so what exactly am I paying for? if they knew they were going to debit me why then did they block me from using the facilities because they should have allowd me to use the facilities, now it means I'm paying for nothing. I demand a refund for the November & December
