Vodacom Staff know not what they do

It is with disgust that I type this complaint, in all my 20 +years with Vodacom I have never received such bad customer service. I spoke to a consultant on Friday and again today, firstly the person I spoke to on Friday no one know's who she is or where she can be found, the second person had the audacity to have attitude with me when asked particular questions. At one point she got quite irate, I didn't say she must become a call centre consultant if she can't deal with people. Then she leaves with a question mark as to whether she actually know's what she's doing or saying because she says Vodacom will get back to me in 24 hours but an sms states 2 working days and to make matters worse according to her calculation 24 hours divided 8 is how long I will have to wait, so what is it 24 hours, 2 days or 3 days and in this time Vodacom aint the cheapest network where data is concerned I'm too scared to purchase and data in case the same thing happens. So what do I do now can someone/anyone at Vodacom tell me that because I refuse to buy another Gig of data and the same thing happens???????????????? Because out of 1.3 megs which generally lasts me 4-5 weeks as we have WIFI at work, was depleted in less than 2 weeks. I purchased the 1G either 27/28 Aug, my contract 300Megs came in the 1Sept and by the 8th September 12h54 I had 95 megs left.
