Vodacom messing up yet again

Yet another brilliant experience with Vodacom, the largest network provider in SA ... I queried almost 10 days ago my upgrade date which states that am only due for an upgrade in June 2021 and that my contract start date was June 2019 ... quite amazing as we are 21st May 2018!! Am told that I need to wait 3-5 working days to get feedback ... got none so called back to be told that I need to wait another 7-10 working days. Why such issues with a large corporate? And I was told that Cell-C was worse so pretty much stuck with no options. Brilliant.
