Vodacom do not care about clients

Horrible service, I upgraded one of my numbers via the internet, only that vodacom creates two new number for my account. I went to the shop in Brits mall various times to cancel and receive credit for this account only to be told it was done. However, I am still being charged- The systems at Vodacom is absolutely horrible. Also, I have cancelled my insurance on my phone more than two months ago, only to have it still charged on my account. Vodacom is a *******, lying business and the majority of the people working there do wish to assist you.
