Vodacom still havent delivered device

I upgrade online on the 5th of April. On the 18th of April i still haven't received a phone call from Vodacom or RAM for the delivery so I phone Vodacom and spoke to a lady called Roselyn. She firstly had the wrong upgrade number (number form 2 years ago) then she proceeded to tell me that Vodacom is out of stock. But when I placed the order it NEVER said that they did not have the laptop in stock. In the past Vodacom would have contacted the client and offered them a different option. No such luck. Now 4 weeks on NO contact from Vodacom or RAM. I am getting fed up with waiting for my device. I think that their service has downgraded in the last couple of years.
