Vodacom Fiber service sucks

Hi, I'm having a really bad experience with Vodacom Fibre. It's been two weeks since my internet link has been down. I have been calling them almost everyday since the 14th of August. Their technicians only came on the 16th for have a look at my router. They spent 3hrs and they couldn't figure out what was the problem. They promised they would update me but they didn't. Since this Monday I've been calling to get the update and they keep asking me to reset the router and still the link doesn't come up. They even closed my case without verifying with me if my service was back up. Then when I called them again this Wednesday they told me that they have ordered a swapout for my router because they believe it's faulty. No has contacted me about this. Yesterday a callcentre agent was also trying to reconfigure the router and promised to get back to me in an hour. She never did. I've lost two weeks and no one is even considering the fact that I'm paying a lot of money for the server I'm not even receiving. I'm upset and disappointed. I want to cancel this nonsense of a contract.
