Terrible service from Vodacom

So I was due for a contract upgrade, I went into the Vodacom branch in Westgate close to Games. I was told I would have to settle my previous contract first so there would be a double payment for 1 month,now apparently its 2 months.I had ask the salesman if he is sure of the 1 month double payment only and I was assured it was 1 month. So that is horrible service from my behalf. The second issue I had was that it wasn't brought forward to my attention that my previous contracts perks would be terminated due to the upgrade. Overall very poor service from Vodacom and their salespeople.For being a loyal Vodacom customer I would have expected much more but once again thanks to them for nothing.
