No Delivery for Red contract

I did my upgrade online on Monday 28 Aug because they advertise that the delivery day is the next day, I received a confirmation online that my upgrade was successful, after 2 day I still have not received my new phone, then on Wednesday 30 Aug I phone Vodacom only then to inform me that something went wrong with their system, the agent I spoke to told me that I will have to wait till the next week Monday or Tuesday for delivery, Up to now I have not received my phone after I had to phone again to hear now there is no stock, This is the type of service for a red contract owner when you advertise all the advantages for the red contract owners.
