Poor service

Hi I called Vodacom @ 9:53am on Friday confirming my online order and was told I qualify for a specific phone and the consultant said she would call me back on the same day, which didn't transpire. Today when I call to confirm the order it has now changed to something else. I have a current contract which is upto date and a fibre line with vodacom, but this type of service is not upto standard.
