Vodacom is a *****

I had R110 airtime loaded yesterday and R55 was deducted for the advance payment. Which then left me with R55 airtime left. The airtime used yesterday was the extra airtime that Vodacom gives you when you recharge and when I went to bed I had bought data for R17 and had R63 extra airtime left in my account plus my R38 but when I woke up this morning wanting to make a call I ha nothing in my account but the data is still there. I tried calling vodacom numerous times with no luck instead my calls get disconnected and I am given no option to speak to a consultant. This has made me very angry because I now have to make a call for work and I can't. Must I now request for an advance that I must pay back again when I know I had airtime? Trust me I hate Vodacom and I wonder why they are still in business, maybe it's because the rob us flat. Do the even know I've been on their network for more than 10 years and this is the thanks I get? I am porting out of Vodacom I'm sick of their nonsense.
