Terrible service from Vodacom

I was offered a data contract with a free WIFI router by Vodacom on the 22/04/15. I was promised delivery of the router on the 28/04/15. This never happened. I then called in on the 30/04/2015 and I was told the item was dispatched to the warehouse. I then called in on 04/05/15 and I was advised it is with the warehouse. I called in on the 05/05/15 & I was advised it has been dispatched to me I should receive it before COB. I then called in today only to be advised the item has been returned as RAM could not deliver. They never made contact. The person I spoke to said the line was cancelled and he would need to re-apply. I gave him the go ahead. he put me on hold and came back a few minutes later to say that the unit was not returned to them so he cannot. I would have to call in on Friday. Now everytime I call in I'm on hold for 15MIN at least before speaking to anyone. So I asked if he could call me back and he refused. That is pathetic. You can call me to get me to buy something but to sort out delivery I need to keep calling in, THIS IS SHOCKING. LOSING A CLIENT YOU HAD FOR YEARS.
