Inability to make calls

<p>I am unable to make any calls from my mobile number contracted with Vodacom on a Smart S Plan. I am experiencing this problem from the 20th June 2016 and visited the Benoni Lakefield Vodacom customer service centre on countless occasions to resolve the issue. Although the manger, Mr Burt Behr was extremely helpful and tried as far as possible to resolve this problem, he was unsuccessful. I have now no idea who to contact. I am currently paying for a contract that I am unable to use. It is impacting negatively on my work performance as I am on call out at all hours of the night. In the event of an emergency, I am unable to make any calls. I am extremely dispappointed with the poor service from Vodacom. </p>
