Unable to help or resolve my problem after 8 days

I phoned Vodacom to upgrade my contract to a VIP package. Someone who I spoke to did not process my upgrade and Vodacom unexpectedly shut down my service on the 30 November 2017. I cant send texts, watsapp or make calls. After 8 days and phoning them every day, they keep on sending me around from department to department and still nobody is willing or able to resolve my issue. This is absolutely ridiculous and terrible service from this service provider, considering I pay them R3000-R3500 every month.
