Horrible Service

I'm so disappointed in Vodacom! I have been trying to cancel my insurance since June. I have been on multiple phone calls with Vodacom consultants and the Insurance consultants. As we speak, I am to receive roughly R600 credit on my account because of the insurance that's still being debited from my account even after my multiple attempts to cancel it. I have an email from one of the consultants confirming my case. I have even reversed this month's debit order out of frustration and yet today, I received an sms stating that I must still pay. This is utterly unprofessional and a financial inconvenience to me.
