SHOWMAX ******** deductions and refusal to refund

I signed up for Showmax I cancelled in January 2023. It came to my attention that on my Vodacom account I was being billed since April 2023. I only realised this in October when doing a query with Vodacom. I cancel AGAIN on 5/10 and yet again I had a deduction. I cancelled AGAIN 7/11 and contacted the so called help line. The agent Malebogo Pholo is extremely unhelpful and actually rude. The blame is placed on me. I allegedly have two accounts, which is not true (I only have one email address). They cannot provide proof of the registration of account nor proof of activity however I must pay no refund will be done! I have requested repeatedly that a manager contact me but nothing! I demand a refund of the R 800 Showmax has deducted without authority for an account i do not have, have not used and has never been validated!!! It is *******!!!
