Ongoing bad service

I've signed a contract with Vodacom. Then after a couple of month there was an increase, not much, but it was not mentioned when I first signed. Then notifications came of a data limit. Still I did not mind, just happy I could still have internet. What else can we do?

Now we don't have internet at all since just after 8. Apparently there is an outage somewhere. How long will this take before it is fixed? I am tyred of all the surprises. I just want what I am paying for.
