Cancelled contract debited

I did an early cancellation of my contract in February, as I was leaving the country. I paid an exorbitant amount for this early cancellation. My phone contract was cancelled a few days later and I was moved to pre-paid immediately.

Fast forward to the 1st March, and my bank account was debited the monthly contract fee, even though the contract was cancelled and ALL outstanding fees paid upfront via the early cancellation fee.

I asked my wife to contact you as she's still in South Africa, but she was just told they can't help her and that I need to contact Vodacom via live chat or an email to customer care. I sent an email to customer care 5 days ago (reference 002BVaH1VDMXFQGK, as per the auto email I received), but have not been contacted at all. I just tried using your live chat, but Tobi the bot is useless and can't connect met to a live chat agent.

I need that money credited back to my account, as that debit order should not have gone off. The contract is cancelled and paid in full.
