Extra billing, no investigation, Vodacom has ******

I have had the worst experience running around for two months.

Vodacom has removed my discount. They keep telling me my term date is over which is why they removed the discount. There are some that agree with me and some that don't. There are some supervisors at Vodacom that want me to pay extra but there are those from customer care that is seeing what I am seeing and have already loaded a service request for me.

Vodacom ows me over R2000. And although I have cancelled all my contracts of the same time, they have allowed one contract to run for one more month.

I need serious help. I'm getting thrown from department to department and no one wants to help me or investigate this. I am an ex employee of Vodacom and I know what's going on. But there's no investigation happening. Please can someone assist me with winning this case. I have all the proof and documents with me
