Debit order after cancellation

As per Afrihost, cancellations can only be done via their Client Zone, no other method, not on the telephone using security check questions or at an office. So when my property was sold, I had no choice but to use the Client Zone route. Was told to do it before the 15th of June for service to be terminated at the end of June. This is exactly what I did. So come 1 July, debit order via Payfast goes off. Their whats app service is a pot of pooh, useless! 4 emails later, I still get a ticket number with automatic reply emails sent via high priority- have you ever!!! Today spoke to a lady at their call centre who has advised me that I will have to use the Client Zone and keep the proof of cancellation, BUT THEY DO NOT SEND YOU A PROOF OF CANCELLATION!! Reading other reviews regarding the same issue, I realise that they are taking people's money after cancellation and therefore it is so difficult to cancel. I have gone into the Client Zone 10 times now doing the cancellation and did not receive 1 confirmation!! ALSO - the call centre agent is telling me that the wifi has been used on Sat 2nd July - We handed over keys to the new owner on the 30th June, we are the only people with the passwords, AND we live 12 kms away now and have not been close to the area since the 30th, how now?? I sincerely hope that when my new home is completed that I do not have Afrihost as a service provider, I will never make use of their service ever again nor encourage people to join their service as I have done to so many people in the past. Disappointed and very annoyed!! Their CEO Gian is sending emails with some sort of gift, No thanks! Sort out your service instead please. I emailed him a couple of times but no response.
