This is Coastal Air. This is a spam call. They are very rude on the phone. I have never been treated so rudely by anyone else. When they called they yelled at me on the phone when I said that I didn't want to buy anything. I have never had anyone yell at me on the phone. They said that they came to my door. I don't recall them coming to my door. Possibly one of my other family members answered the door. In either case, the rude tone of voice and yelling at me was not OK. A business should never treat a potential customer this way.
