High level complaint Vodacom

Hi Hellopeter, I am writing this as I am so furious with the Vodacom cawhy this was happeningcenter. I have a Router I was tired in a 24 months contract, it ended on the 22nd December 2019. I was not informed that if my contract ends I would be charged normal rates. On the 27th January 2020, R1,007.76 was deducted from my account when I only agreed to pay R500.56 I ended up calling the call center to my understanding that would have a better explanation as to why this was happening? I've had people shout at me, quote terms and conditions the list goes on. 1. Spoke to Celest who rudely told me I would need to go the branch and sort this out as she deals with upgrades line drops. 2.Called customer care spoke to kateekani she screamed at me saying she will go crazy on me asked to speak to a manger twice was denied finally Dean came on the line the agent was still taking about me in the backgroung. Is this how you treat your customers??? I just wanted a refund and to upgrade my package are you not willing to retain your customer?
