Upgrade TV service

We have been trying to upgrade our TV service for a couple of years (true).  We have very old boxes and now no longer get "on demand".  We have been told: - the signal to our house has to travel so far service will be spotty,   we can dig up your driveway and drill holes in your house to run a cable through,   the machine to drill under the driveway does not have enough room and will destroy your neighbors lawn,   this is a vast amount of work and I am not qualified to do it,   you need an amplifier(put in),   you do not need an amplifier (taken out).  There are more but these are the basic.

Ideally we would like to have Xfinity TV, internet and voice service and at a minimum just upgrade TV service to new boxes and better service.  Since we currently have TV service we do not understand why we can not upgrade.

Perhaps a senior tech would be available to come to the house and assess the situation and give us a reasonable explanation on why an upgrade can not be done.  We are hoping that new technology is now available that will allow us to upgrade.

Thank you for whatever help you can provide
