False promises and still no phone after an upgrade

Good day, i did my upgrade online and over the phone last week Thursday, I was promised delivery the next day. On Friday at 2pm I contacted Vodacom because no had had been in touch with me regarding the delivery. I was told that they tried to reach me on a number with no success whereas they used the incorrect number. I phone Vodacom again this morning and Spoke to Amanda, who then transferred me to RAM. Their agent Millie was rude and told me the phone will be delivered tomorrow. I want my phone today or Vodacom must cancel the upgrade....
