Vodacom errors and them not paying my money back

Vodacom has been billing me for over 2 years for an insurance that I cancelled. I logged a query and the cancellation was submitted but the system failed to process it. They worked out the refund and took my banking details for refund. The consultant then makes an error and instead of processing my refund to my bank account I provided, they pit it into the vodacom account. They were to lazy to complete the some blue form.

Second error, yet I'm suffering the consequences I have been calling multiple times for them to pay my money into my account and they keep saying ok, but I haven't received it. It's been over months now. I need my money now as I am in hospital and need my funds. I have recorded the conversation with consultant tanya hempton and then manager Nozi mshumpela. All I want is my money back and yet I haven't received it. I think these errors that vodacom claims to have are just excuses not to pay my money.
