Viva cannot cancel a simple contract

I am extremely enraged with Viva Gym in terms of the cancellation process.

Firstly, after my contract had come to an end, I was not informed that the 12 months was up. Instead they changed my contract to month to month one and charged more. The decency of a call was too much to ask for.

To top it all off, after I requested a cancellation of my contract I was told that I was unable to do so between the 25th of the month and the 1st. I therefore did so on the 3rd of September 2018. Now I am being charged for gym fees for September even though I requested cancellation in August. Why should I pay for a month for a membership which I obviously want to cancel? Why should I pay in order to cancel? They have tried debiting me twice already. I have not received a phone call once!

Their system says my contract is cancelled yet they are still trying to debit me. This does not make sense. I was told that they cannot debit a cancelled policy but that is a lie as they are still trying to do so.

I hope they realize I will never pay for something I don't intend to use.
