Delivery of Sales Order not met

Order a phone online, Vodacom phones back. Do the application online and its approved. Call Centre agent says delivery takes 3-5 days. If I knew it will take longer than that, I would not done the application online. Phones Vodacom to confirm delivery phone has not even been dispatched to RAM. Phone Vodacom again lady says she escalate and phone me back. (Still no call back) I tweeted to get the matter escalated, got a message back you can cancel the order if I want with cancellation department. No phone call to maybe try to resolve or try assist with some way. Great Service. I have a other contract with Vodacom maybe I need to look at a different provider.
