Not being able to cancel on time!

I asked on the 26th October to please cancel my membership, as I can no longer afford it. I kept trying to phone, but kept being told the number no longer existed.

I finally got an email reply on the 4th November, to be told it will take 20 working days to cancel, and then will still be billed the next month. I asked to cancel, and to please be from the date that I originally asked to cancel. I have yet to get a reply.

If my Maths is correct, this will now mean I will be paying for 4 months of gym membership, which I DO NOT want to do!!!
