Vodacom Minutes is a ****

Vodacom is *********** their customers forcing them to buy daily voice bundles and not giving realistic minutes. I need 250 minutes per month. I have been buying minutes like this for years and my contract that I signed was based on buying 250 minutes per month. Now I need to buy 100 daily? That is over 3000 minuts, who in their right mind speaks on the phone so much? Customer care said they can add 250 minutes to my account but I am paying over R1100 per month, why would I want to pay more when I could just use my airtime. Like I have been doing for YEARS! I will be looking for a different provider for ALL my Vodacom contracts because of this.
