Vodacom call centre is useless

This morning I phoned the Vodacom call center because I am having network connectivity issues and I can't use any web based apps on my phone. After waiting for about 15 minutes to speak to a call center agent, I finally got through. I explained the issue to her and she asked me to test the sim card in another phone. I told her that no other phone in my household uses the nano sim card that my phone uses. She then hung up on me without offering me a solution or a way to fix the network problems. It's been about an hour since I phoned Vodacom and still no one has phoned me back to see if the issue has been resolved (it hasn't). I am no making any unnecessary demands, I just want Vodacom to provide me with the service I am paying for. Will someone from Vodacom PLEASE phone me so that we can resolve this and move on!!!!
