Vodacom deducting funds without a contract

Warning: Avoid Vodacom at all costs! I had a data contract with Vodacom that I struggled for months to cancel. Despite being told it was cancelled in September 2024, they continued to deduct money from my account in December 2025 and January 2026. When I tried to get a refund, I am being given the run-around by their customer service team. Has anyone else experienced similar issues with Vodacom? How can I get my money back. I NEVER want to do business with Vodacom EVER again!!!
