Useless Vodacom Call Centre

I’ve been trying since Saturday 27 Feb (today is 3 March)a couple of times every day to give notice on two contracts and it has been absolute torture. Calls not answered after 5 min and then the call is just cut. Calls picked up and then dropped while waiting. At this moment I HATE Vodacom and want to move each and every contract to a new service provider. Also calls are picked up but no one answering on other side. You hear laughter and chatting but no one attends to the call. So how the %*£#* do I cancel these contracts. Vodacom your image is “in sy moer in”. Absolutely useless bunch at the Vodacom Call Centre.
