Vodacom, worse than a Government Dept

Went to Vodacom in Mall of the South yesterday to do an upgrade for my handset. Long story short, lots of uming and aahing, so much that I had to say, have to go, get the info all together and call me once you have it so we can complete the transaction. 24 hours later, nothing no phone call, Zero. So the question is would I still be sitting there waiting ???
