Vodacom **** subscriptions *****ing my airtime

I have been experiencing problems with vodacom busy subscribing me to things I know nothing about. I don't even get the content of the 'so called subscriptions'. I have been calling there customer service line numerous times to cancel and they say they cancelled and after some time new services are added and *****ing my money. I want all my airtime from when it first happened in November 2017 till today 30 March 2018. If not I am switching network. In the past I never experienced such. I am now starting to hate Vodacom. I have been with vodacom for almost 20 years and have not experienced such.
