Vodacom and their WASP services

I have been charged for a few months for content services which I never subscribed to, I have every month sent this to Vodacom and they have not responded, my contract is due for upgrade and I do not think that I will be renewing it, I have just had endless problems with Vodacom, I have been their client for over 22 years, they keep saying they will credit me but it never happens, yet every month I contact them to unsubscribe me, and almost daily sent a SMS to 31050 and 30333 to STOP ALL services, nothing is done about it, SO NOW VodaDOM I want this fixed NOW, no excuses no promises FIX IT, I have proof that this WASP services is from your Vodacom APP. I want all of my money that you have deducted from me for these WASP services returned immediately or I will institute legal action as you cant even tell me when and what I allegedly subscribed to, FIX THIS NOW, I have less then a month where I can CANCEL my contracts with you. I have over 6 or 7 contracts with you, I will move, I promise you that.
