Worst Customer service , Completely ignored

on 13 July I phoned Vodacom sales and was approved for an Uncapped data contract, the router was in stock and I waited for delivery. After not hearing from the courier a week later I phone after-sales and my order hadn't been dispatched and I was told my account was showing some "Invoice" error. After multiple escalations, emails, and phone calls with promises to get back to me over the next couple of weeks, I had only one phone call just to tell me my query would be escalated yet again to a different department. No feedback, no one else contacted me, and my order 3 weeks later was still not dispatched with the same error showing. This is possibly the worst customer service I have ever received and felt completely ignored. I have now cancelled my order having given up on the miracle of Vodacom getting back to me with a solution.
