Passing the buck on horrible service

Imagine dreading to upgrade your device every 24 months because each time the experience turns out to be a horror story. I am sitting without a phone for the second week in a row as we simply cannot get Vodacom to process our order. It apparently reaches the quotation/ confirmation stage and then no order is actually placed, all the while we are losing business and awaiting delivery of the device as repeatedly promised. No-one can be bothered to actually process the order and the consultant simply blames the previous consultant. They simply pass the buck and cross-blame. When trying to get an answer and expressing my disappointment, I get the infuriating response from them: "We are sorry you feel this way." Horrible service each painful time we need to get service out of them, yet the (very expensive) package is paid in full each month. Every time we have to threaten to cancel our contract and go to extra lengths to get any kind of response from them.
