Vodacom does it again

I have been a Nashua mobile user and on the vodacom network for close to 15 years and never have my package tariffs been increased. I have been increasing my portfolio with this service provider year on year. Now with 4 contracts I have been slammed with a total tariff price increase of R80 and it is not legal and also not fair to a paying customer. I signed 24 month contracts and feel that I do not benefit at all from any rewards programs and will also not be getting any value out of this increases. I do know that the network providers are under pressure but so is the consumers because of increased taxes, fuel, food, inflation and other prices.
