We appreciate you asking your question here in the Xfinity Forum, we are happy to help. The tech who had to come out to replace your line more than likely had to put in a service request for your local line techs (which is a different crew) to have the line buried. Based on when the line was replaced, the burial of the line may have been delayed due to restrictions that were set in place because of COVID-19. I'd be happy to investigate to see if a request had already been created, or create one for you in necessary.
