Absolutely Frustrated with Vodacoms Customer Service!!!

Absolutely terrible customer service from Vodacom. I upgraded my contract on the 18th December and still no delivery of my device. Ram says order is on hold and will only be delivered once Vodacom gives the go ahead. I have been calling Vodacom on *** everyday since the 23 December and keep getting told delivery will happen tomorrow but nothing happens!!! When I call Ram the keep telling me nothing can be done from their side until Vodacom gives them approval and the order is released
