Vodacom misleads customers to take their hard earned money

In December I received a call from Vodacom, they saw that I don't use the 500 sms I receive and asked if I would like to have it replace with 2G data. I asked if it would cost more and he said no, its a straight swop. I agreed, and as we went through the steps I said, numerous times "as long as I dont have to pay more" / "as long as it does not cost more", and each time he confirmed that it will not. On 16 Jan I checked how much data I had left, on the app, just to see that my bill iwas R292.24 MORE than it should be. I phoned the call centre and was told to phone back during office ours. The next day the lady I spoke to said she will escalate it and will get back to me in 24-48 hours. 10 days later and still no feedback. When I phoned her she was not in and she has not rep**** to my message. The amout was taken from my bank and I had to reverse it, causing extra bank fees that I now have to pay due to their false and misleading call centre agents. I have been with vodacom since I got my first phone back when nokia was still the size of a brick, but that does not matter, as loyalty means nothing to these big companies.
