Vodacom a liability

I have had preposterous service from Vodacom over past few months regarding my network issues and still has not been resolved. I am left without adequate data speeds having to wait more than a minute for a page to respond. How do I prep for my midterm exam?? Secondly I made the hellopeter consultant aware of my second issue as I am not receiving calls from certain people she assured me that it was a setting on my phone when I continuously responded by saying it is not. She even went as far as saying she has 15 years' experience in telecommunications and I must go to a vodcare 30 KM from where I live. I then did my own research and found and resolved my on problem and all I needed was 15 seconds on google. When calling customer care I again had to explain to the consultant what she has to do to resolve my problem after again being told another story. My query is thus resolved after having to do Vodacoms work. I want plain and simple service I PAY AND YOU GIVE ME WHAT I'M PAYING FOR. NOTHING MORE NOTHING LESS!!! And without me having to research train your colleagues on how to resolve my own issues.
