Lack of Honesty

I did an upgrade on the 22nd of November which included a router and more data allocation. Since the 22nd of November I am yet to receive the data allocation and the router. Throughout this time period I kept calling and the agents said it was awaiting despatch.

I kept calling asking when it would be delivered and today around 15:45 the agent I speak to says it's back ordered and if i keep calling my number would be blocked. How did it go from awaiting despatch to being back ordered?. I am really disappointed with Vodacom for the lack of honesty and as well general respect for their customers
