Wrong billing

I received a email today to say the my debit order did not go of, my contract ended 31 of Jan 2020, and that I own 2month. On the 2 of Feb I was at the gym to cancel my contract which the lady told me the debit order does not reflex yet. But she will keep track of it. I AM so ANGRY at Zonefitness. I feel that when your contract ends the gym must contact the member or members and ask if they want to be on a month to month contract.Zoneftness opened on the 24 of Aug according to the website and you charge me of the month of August, was not even at the gym.
