Vodacom

Vodacom upgrade me in april on the phone. The amount that they give me and the amount that they debit me is 2 diffrent amounts. I have been phoning them from may month still today its not been sorted out. I want to stop my debit order. I have been trying to get the voice recording went to vodacom shop twice cant get it. I have the sms they send to me with the amount that they gave me over the phone. This is my last contract with vodacom. Im with them for 30 years. Now im done with them. Never again
