Dissatisfaction with vodacom service

Hi..I'm kathija, I'm extremely disappointed with vodacom,I have currently 300gigs day and 300 gigs night..my contract number *** is due to end end of November. I received a call from vodacom consultant offering me a better package deal that I will receive 250gigs day and 250 gigs night together with a laptop and router but I have only received 150 gigs day. I was further informed by the consultant that due to my excellent payment record,they offering me such a great deal. I currently have 2 contracts with vodacom. I called customer service and they cut me my call.. vodacom is useless and I'm extremely upset..if I do not get what is promised to me ..I will take this matter further. Kindly contact me on ***.
