Shocking lack of service + failure to communicate

I have a monthly contract with Vodacom for both airtime for my phone and also data for my computer. Today being the 1st August I expected to find the full month's worth of data on my computer when I sat down to work. All I got was messages from Vodacom saying I was out of data. How could this be when the monthly new data comes down at the beginning of the month? Urgent work issues started to pile up. I called my local Vodacom shop (Caledon). Seventeen times between 8.15 am and 1 pm. The number was engaged or unanswered every time. I called the Vodacom customer care number and was told I was in a queue. I was desperate for answers so I waited in that queue for over 50 minutes with no result. THIS IS SHOCKING LACK OF SERVICE AND MY ISSUE IS STILL UNRESOLVED.
