Porter,
I have watched our local TWC bury cable on homeowners' lawns. They slit-trench, which is much less invasive than having your lawn core aerated. There is no need for dirt to be "filled" - none is removed in the first place. It is a very slick, quick, nearly benign operation. I would assume that your underground cable was handled in the same manner.
BUT - TWC never should never have done the work without your permission. I would certainly bitch over that. TWC seems to love installing a new drop whenever a customer has a problem with digital cable and/or high speed Internet service. I went through the same situation 3 months ago and for the same reasons. That new cable is still draped across my lawn due to my persistence.
I informed the installer to not schedule burial since I will be trenching the lawn this summer and I'd prefer to not cut through a buried TWC drop. To be extra safe, I phoned TWC and informed them that our back yard is fenced because several times per day we just open the back door and release our two Dobes. TWC now knocks on my front door before entering my property. I'm in their computer as "the owner of attack dogs." A small but effective fib.
Always assume that the person you are dealing with is a moron and take defensive measures. You won't regret it.
I feel fairly certain that your cable was slit-trenched, but you still have the right to bitch at TWC. One month's free service should be a reasonable compromise from your vantage point since you really suffered no damage but TWC did ignore your requests.
If they actually trenched and they did damage to well-established trees, then you could have a serious legal issue. But you should still realize that 80-100 foot, well-established, healthy trees are generally very robust and often handle such trauma rather well.
The down side is the fact that non-trivial trauma to well-established trees often won't manifest itself for many years. It is often difficult to go to court in front of an ignorant judge and plead you case that your trees may possibly show signs of distress 6 years from now. The judge isn't an arborist and his "common sense" will often over- ride any expert testimony from an trained professional. Sad but true.
Good luck, Gideon

26th. I instructed him that I wouldn't allow any digging, and I didn't want the cable installed, as I have several old growth trees along the digging path within 5- 15 feet.....incidentally, I was never given a reason as to why I needed a new cable- my service has been great!
So, I'm out of town for vacation later that afternoon, through today(Sunday the 23rd) and return home to find the trench cut, cable buried and filled. Several trees had root systems compromised- 80 -
100 foot trees that I'm interested in keeping around for a while. Heck, I'd have spent plenty of money out of pocket to hand dig, and or reroute the cable to avoid screwing up something that takes 80 years to grow. Not to mention the trees die and I'm out $1000 minimum for cutting and removal per tree. The cable was installed outside of the easement.
What's my next step- (I will be calling an arborist to consult on the damage as a starter)
