Vodacom once again proves they are useless

In December last year I upgraded my account and explained that I was leaving in three days and whether the device can be delivered in time and was told that yes it wont be a problem. On the last day before I was about to leave I contacted Vodacom again because all I received was spam and no further communication. I was then informed that the device will be delivered the following Monday because Vodacom *****ed up. I asked to please not deliver it I will confirm a date once I'm back. I then received a call from Ram Couriers on the Monday to inform me they are at my house to deliver. Vodacom wasted their time and mine and *****ed it up again, I then explained to Ram that I specifically asked to postpone delivery. Now that I'm back Ram has advised me that the phone was sent back to Vodacom, I'm again on the phone for over an hour to finally hear that now the upgrade will need to be reversed and a back office person will contact me within 24 - 72 hours because no one is competent and no one dares to commit. Everything Vodacom touches to date was a ***** up. And now Vodacom will copy and paste a response that they will contact me, I'm still waiting for the call on my previous query
