Vodacom and Service Delivery - A joke

I have stopped counting the number of times I wrote bad reviews on Vodacom. Sorry to say there is just not a commitment to good service delivery within Vodacom. I called two weeks ago to check on available updates on my different contract I have with Vodacom. I ended up agreeing to upgrade one of my lines and did everything that was expected from me. A day later I got the call to confirm my request and was informed that the device would be delivered within three working days. It has now almost been a week so I called to find out when I can expect delivery. Only now I am told that they have no stock of the device I requested. If I was told this in the first place, I would not even have considered an upgrade. It is so ********* to hide information just to close a deal. Needless to say, this is yet another line I shall keep until the end of the contract and cancel. So much for rewarding loyalty.
