VODACOM CHARGING ME ON A CANCELLED SUBSCRIPTION

I cancelled my Apple Music subscription in March 2021. Nevertheless, I am still being charged R60,00 pm by Vodacom and this is simply added to my debit order each month. Vodacom told me that I must cancel my subscription with Apple. I told them that I cancelled it in March 2021. Apple has confirmed that the subscription is cancelled since March 2021. I want a FULL REFUND of all the amounts paid to Vodacom. The refund due to me is R1,320.00. Vodacom has told me that they don't do credits, I must speak to Apple. Apple confirmed that they have not received any payments on my account. It is some kind of stuff-up between Vodacom and Apple and I am paying for it. They must stop charging me every month and give me my money back! I have been on the phone today for at least 2 hours @ R2,500 per hour which is the time that I have been unable to do any work. I AM ABSOLUTELY FURIOUS! I have proof on my Purchase History that Apple has not received any subscription payments since 1 March 2021. Is there anybody you can talk to there? I have spoken to the Call Centre three times today and it keeps going round and round to the same thing where they say they have paid Apple when in fact they have not. Vodacom does not have any work order no. PLEASE HELP!
