From the 15th July I stopped receiving messages on my phone and I logged the complain with Vodacom, they have been closing my request without being resolved and today I spoke to the manager Branton Matthews, he told me there is nothing they can do, they can only log another request with back office and it's of their hands. I'm paying for this contract and I can't get help. I asked them what must I do with the sum card that is not working and he said there is nothing he can do. My job is on the line because of this. Even their 3rd part they couldn't resolve it
