Cannot get issue resolved

We have been without internet access for three weeks - Century Link accidentally cut our cable doing their own work on 12/18 and we have been trying to get someone to fix it ever since. I have been on the phone or on chat every single day trying to get someone to come bury our new line. They have sent 4 different technicians who all say we need a construction team to come dig up the concrete in the alley to bury a new cable. But every time I try to get an update on if this is actually in the works I get a different answer or a false answer. For instance, the chat person yesterday told me the construction team was scheduled to come today between 11-6, but they never showed up. I chatted again and the person said they had no record of anything being scheduled for today and that there is just an open ticket for our property with no scheduled date for completion. I continue to ask for a status update to make SURE someone is working on this, and no one will give me an answer or proof that they have any intent to fix this. We are not able to work or educate without our internet and I am wasting hours a day dealing with this. What do I do to get this fixed??
