CALL AVOIDANCE for 39min!!!!!

I called VODACOM today 3 times today to finally come through to an operator who refused to acknowledge me even though I could hear them breathing into the phone and their colleagues in the background. I refused to disconnect the call from my side as I have trying to get hold of them the whole morning. I repeatedly tried to get the operator to speak to me and held on the line for 39MINUTES!!!!!! while I was listening to the background of other operators doing their jobs and chatting about their weekend . I managed a call centre for a number of years and this is one of the WORST CASES of CALL AVOIDANCE. I HAVE THE CALL TO PROVE THIS!!! How can you allow your operators to treat your clients that way. I then spoke to SHANE LOUW, manager of the call centre and he assured that me that he will get back to me. This incident happened at 10:07, I spoke to Shane at 11:12 after holding on for another 30min, it is now 14: 40 and no-one has come back to me. I would like to cancel my upgrade (which is on backorder no: 858119 till September 20th and I already placed the order on the 19th August already) and will be cancelling my remaining 3 contracts with Vodacom which is due in January 2016.
