Worst experience with Telkom mobile!!

I have never had an issue with Telkom up until now. I cancelled the free me 1.5GB deal with effect the 17th July 2022. Telkom debited me on the 31th May 2022 and I reversed it since I have been struggling to cancel this service after my contract ended with them. I received several SMS's to make payment of which I did through thr website on the 9th June 2022. I received my invoice and confirms this payment but then on thr 15th June Telkom debited me and I tried to query this with the chat agents and on Facebook messenger but no one is willing to help me. The chat agents end the chat when I keep asking to provide me me with an email address so that I can send proof of this debit order. It's such a struggle with the self help and no option to speak to an agent on the phone. I have requested call backs sent emails to ***. I want my refund please. I also see a debit order that will be going off end of July. It should not be the full amount since my cancellation is effective the 17th July. This is so frustrating!
