SADV Owned by VUMATEL simply ignoring any request or raised tickets

Dear VUMATEL

VUMATEL owns SADV I am turning to you and social media as dealing SADV and their helpdesk is absolutely useless.

End of April we have canceled our SADV subscription to be canceled at the end of June. This due to immigration. We did this via the portal and it also clearly stated to be scheduled to be canceled. After June, July came and went and another invoice, then August came and went and another invoice for SADV and the line is still not canceled. I logged call on the portal and emailed the support helpdesk but so far nobody seems to be interested in answering let alone cancel the line and subscription. We have been loyal clients for over 6 years and we took the necessary steps to make sure we canceled on time. Unfortunately SADV doesn't seem to thing we deserve a good treatment and keep debiting our account for a service we canceled a long time ago. This is absolutely unacceptable and it would be a great case for the consumer protection act. We moved out of our house on the 30th of June. We have left South Africa on the 11th of July. We have no access to our old phone numbers anymore. Is there anybody that is willing and can help in this matter. We also would like to be reimbursed for the 2 months that we have paid while we already have canceled and if another invoice is raised we will take this further.
