Buried Cable Line/Technician Charges

I am extremely frustrated and need help.

My cable wasn’t working correctly so had a technician come to my house. He had to run a new cable line to my house because the old line was bad. For some reason, I was charged $100 for this visit. The cable line was not buried and the technician told me someone should come back to bury it.

Fast forward to Friday 7/11, a man comes to

bury the line. Spends 3 hours in my backyard digging a trench and then DOESNT BURY THE LINE and leaves. I get a text from Xfinity saying the job is complete.

I now have someone coming back tomorrow morning. I talked with an agent who said they would waive the charge but just got an email saying that i am being charged another $100 for this.

So I am now out $200, my backyard is a mess, and the job isn’t complete. 

I need help getting a refund for the $200 and I still need to get this fixed.
