Vodacom lying to customers

I did a telephonic upgrade last week, and was told the phone would be delivered early this week. When I followed up with Ram Couriers, they told me numerous false upgrades were done, and therefore Vodacom had not given them the go ahead to release my phone. After numerous phone calls and e-mails, we received a phone call yesterday afternoon from Vodacom saying that the phone would be delivered in the afternoon. When I followed up this morning with Ram, they told me Vodacom has NOT released the phone, so why does Vodacom phone us and lie about the delivery??? And surely it's not so difficult to check that it's a valid upgrade? Fed up!!
