Worst internet provider!

I'm furious! Never in my life had such a bad experience. Friday night someone came to test my line as it said los of signal. He tested and CUT MY LINE IN THE HOUSE. Saying it's a faulty cable. Promised to see me Saturday. It's Monday and when I logged a call for the utmost time, they said the issue is resolved! How can it be resolved when the line is cut? You can't get anyone's numbers or Manager nrs to escalate this matter. It's absolutely pathetic!
