Most Frustrating Company to deal with

You are the most frustrating company to deal with, you text me numbers to phone that are no longer in use, I get cut off after 18 minutes on the line & no one phones back, if I had to rate Vodacom's customer service out of 10 I would rate 0. I am trying to cancel my contract on *** & trying to make *** pre paid to be paid month to month for three months now & i am still struggling. Can someone please phone me, Craig Whitehead on ***
