Vodacom does not answer a phone . Ironic!

How is it that a telecommunications company can not answer a phone. Since last week I am trying to get hold of Vodacom shop in Vodacom world. Their phones just ring with no answer. When I call Vodacom world, they keep on rejecting my call. A week ago I wrote a 4star compliment for Vodacom, congratulating them on their staff great performance but that seem to be a once in a lifetime event not to be repeated. I clearly made a mistake to renew my contract but will take necessary steps to migrate to another service provider. Absolutely disappointed to think the only platform to communicate with Vodacom is on Hello Peter.
