Vodacom useless two months later, no service

I have been busy for more than two months now to get my vodacom compaint resolved. Every week i have to phone only to be told that my complain will be escalated, then mr Ncobo tells me three weeks ago he will personally handle my complain, up and till today not once did he bother to phone me, Vodacom is not bothered to solve my complaint, suppose its because they gladly take my money every month, worst service ever, any other company will look better after their clients. Vodacom service sucks
