National Grid

The contractor doing the tree pruning for National Grid left a flyer in my door, you know the one that says, "sorry we missed you". The information said they were doing "routine maintenance trimming" in my area, and if I had any? To call the pruning company rep whose name and number were listed at the bottom of the sheet, or National Grid at their number.
Well I have a concern about a large forked oak tree on my land that in a near future storm will probably split in two with the largest portion landing on my service line from Grid's last pole to my house.
The tree company rep was very prompt in returning my call the very next day, explaining that they were performing routine maintainence only and that I would have to call N. G. about this tree. Well I did and the woman I spoke to took down my name and number and told me some would contact me to look at it in 3-5 days. I said fine. Two days later I arrived home to find another "SORRY WE MISSED YOU" note in the door explaining that the tree in question did not pose an immediate threat to my service line, so they would not cut this limb.
I was upset that they never called so I could meet them at my home. The person sent out did not have the courtesy to leave their name. I did not call them back because the limb is 10' above the line and yes is no immediate threat, but this is July stupid. It will be a problem in the next major snow or ice storm this winter!
WhY do these companies continue to avoid customers and leave insincere notes that is say SORRY WE MISSED YOU" when they really mean YIPPEE WE DON'T HAVE TO TALK WITH YOU!
