Disgusted with Vodacom

Vodacom really needs to catch a wake up with their accounts department. My account is up to date but according to them i am in arrears and every week now they seem to bar my outgoing calls. I have tried again many times to reach them on 135 but its a struggle and a mission. So i choose to write up about them. They seem to be failing. I am fed up with Vodacom and would now take to social media to advise people not to become a vodacom customer coz they seem to be falling. More than 12 years i am a customer with vodacom but they are now becoming patheticly greedy.
