Lying vodacom

Vodacom has been sending me sms for vodapay 1GB data for R1 however I was never able to buy this product when eventually attended by tandeka lady it was explain that I can't do anything about it it's promotional. I personally spend over a R1000 every month with vodacom guess what me and 5 of family members will be destroying our Sim cards of vodacom and rather join another service provider that doesn't bull**** it's customers
