Debit Order Continue to be deducted past their contract Period. Notification to Vodacom via email are ignored.

I have emigrated to Portugal 2 years ago and depite my emigration, decided to honour my Vodacom Contract in South Africa. When the Term period finally ended, I contacted Vodacom via their customer care email address as it has been impossible to call their landline or whatsapp. It would appear that staff at Vodacom have taken a long leave "work from Home". I have no replies to my emails, except for the read receipts. I have asked Vodocom to cancel my account in SA and stop the debit orders. These are also sadly ignored. The trail of my correspondence to Vodacom leaves me 2 options, 1) Make this known on your platform, which has worked for me in the past or 2) take this matter to the small claims court. Unfortunatley if your subcribers have a better solution, I would welcome this
