Vodacom caller KNOWS nothing

I was totally shocked in the call I received from Vodacom after we had experienced money debitted from our account without permission. We have been so loyal to Vodacom for many years. The person who phone me was awfully rude and had no manners in the first place. Then he tells me Vodacom has the right to do what they did. We have a contract signed and then he actually blames the branch for misleading us. Then he tells me what his supervisers said, but when I asked to speak to his superviser he tells me there is no superviser. Your people, with 20 years experience, knows nothing. They dont ever know how a contract works.

Thanks to our Vodacom branch which helped me and also differs form your Vodacom Caller.
