Vodacom has so many complaints they can't even respond to customers that want to upgrade!

I have app**** several times online to upgrade my existing top-up contract for a tablet. How many times should one apply to get a response? Phoning is of no help as I don't have time to wait ...... and wait for someone to answer. The response is also ridiculous!!!! Please try again..... What are you serious!!!!! Oh and don't even try to go into the store to ask for help in Kimberley. Response....... You app**** online.... continue online, we can't or "won't" assist you!!! The best is yet to come!!!! Try sending an e-mail ........ This is the response please phone!!! If I had the time to listen to people drone on and on..... I would have gone to store to stand in a long line, with my children that can only wait so long OR I would have phone had I wanted that option. Why advertise something so amazingly convenient when it does not work. Seriously where is you customer care? My husband and I have been with vodacom for 20 years. Are you hinting that it is time to change????
