Telkom Service Cancellation being dragged out

I completed the process online to cancel all my Telkom products on the 3rd of May, giving my 30 days notice. I received three emails immediately to confirm the requests and that someone will contact me. To date, no one has contacted me and my Telkom service is still active - more than 30 days notice. People warned me that this process will be dragged out by Telkom to keep billing me. I hope this is not the case and that this is simply an admin failure. Will someone kindly contact me to have this resolved? I need to know exactly when my Telkom services will be cancelled in order for me to make arrangements with my new fibre providers. I would prefer this cancellation date to not be a surprise.
