I wasn't even aware the service call was scheduled (although, to be fair, we were out of town for three weeks, and returned home on Wednesday 6/22 to find our digital phone out of service. It wasn't restored until Thursday.) However, the technician did not even knock on the door when he placed his door-hanger; which is too bad because I think we have some wasps in the attic I would have liked to have brought to his attention.
