Buried Line Damaged by Xfinity

A neighbor was having a new line trenched to her home, when that crew hit my line and severed my connection. The local utility finder service had marked the area, but missed my line. I asked the crew to stop digging until the locater service came back out. They refused and I was told that would take 30 days. Not true. I called the locater directly and was told they would respond in 2 hours, but Xfinity had to call them with the previous ticket number. The crew refused.

They spliced my line together with an indoor connecter, and wrapped in in vinyl electrical tape. Being a retired electrician, I know this is not an accepted practice.

My "gig speed" is as of this writing at 19.4 Mbps download, 13.2 Mbps upload.

Can someone please contact me about replacing my damaged burial cable?
