Vodacom OVERCHARGING existing customers

To this day Vodacom would rather require me to pay an extremely high price for data (20Gb day, 20Gb night), refuses to allow me to move the data from night shift to where I need it the most or even let me combine the data into one combined 40Gb data. The last attempt they wanted me to pay more than I am already paying (R504/pm). yet I am seeing Vodacom offering contracts for new customers at 40Gb/pm at R399. And more recently they had promotions for a 90Gb contract at R299. Is the customers that Vodacom have now little more than Cash ***s for the profit of Vodacom? How can they claim to be the best when they have the highest data price that there is for some existing members.

Unless that is what they really meant with being the "best".
