Not meaning to doubt you, but if you were not home,
1. how do you know that Service Smart did the trimming
2. I received a notice from Seco instructing me to trim way down all the plants around the electrical boxes or they would do it as they needed to always have easy access. Could they have hired Service Smart or some other company to do that task?
