Vodacom cancellation

Good morning I wrote a while back mentioning Vodacom extended my parents contract without permission. Amazing that they do a 3 year extension for an 87 year old. I have tried to phone the number ***. They promise to get back to me. We have repeatedly been to the Northgate branch with no success. After my last review on your site Deane phoned me from ***. He was very friendly and promised to get it all sorted out. That was on the 12th January. Nothing has happened since. Greetings Kingsley ***
