Afrihost Takes Additional Money on 1 Month to Month Contract

I have 2 x month to month connectivity contracts and cancelled them on 30/07/2018. The Popup on the Client Zone clearly stated that it will be cancelled and nothing around another month which needed to be paid since it is MONTH TO MONTH which is the end of the month. It is a month to month contract and can be cancelled any time, no cancellation timelines or conditions were agreed to. When I checked the debit order continued on 01/08/2018 I queried it to be refunded since the Client zone still showed cancellation being processed e.g it was a Afrizone service issue not cancelling these 2 contracts since nobody attended to it for 3 days. I got a response back saying it will not be refunded since the Afrihost Billing system ran on the 23/07 already. I do not care when YOUR billing system runs the contract is month to month and has been cancelled but not processed by YOUR Team in time.
