Service lacking

I'm very disappointed and annoyed with Vodacom service overrall - I have been a VSP subscriber for over 20 years - my current PRE PAID number which i have had for OVER 15 years probably, has been suspended. When trying to call Vodacom to enquire, - that in itself was an impossible task as most numbers are no longer in use, or you're not able to get through to a human to speak to- Upon numerous attempts, i finally managed to get through to someone, only to be told that my number was moved from contract to pre paid - IT WAS NEVER A CONTRACT TO BEGIN WITH. -
