The PVC conduit under the concrete is a good idea, although this one seems to be poorly installed and patched. At least caulk the end of the PVC. The biggest issue I see in your pictures is the loop of cable hung on a water faucet. That is unacceptable under any circumstance.
The drop installers typically coil the wire up like that temporarily. A tech will complete the install.
I've asked a Comcast employee to help you. You should expect a reply in this thread.
