Dig around the house

Hi, I'm trying to dig around the house. There is clearly an Xfinity cable buried here and comes out of a conduit, but weirdly we got this response from our 811/ITIC ticket: "Comcast has determined there is no conflict based off the information provided." I'm also trying to locate the buried Xfinity junction box so I can safely work around it without causing further damage. Can I get in contact with someone from the local team (Xfinity local project manager)? Thanks so much!
