Vodacom installs cables but damages driveway

Vodacom has been all over our neighbourhood installing fibre optic lines, this is the good part, the bad part is that they cut through our drive way to do it and havent repaired it. One day I leave for work and they have cut a meter long hole from one side of our drive way to the other. They didn't ask or say a thing, fine, but they replaced the bricks of everyone else's around us but not ours.. Whoever the contractors are have disappeared and our driveway still has a massive hole across it. How do I solve this?
