I received a few calls from 407-444-5656. If they don't reach you, they rudely hang up and do not leave a message. When you try to call back this number as it appears on your caller I.D. you get a message saying the number is not in service. They called again today and I answered, The woman said her name was Marie, from Fresh Air Air Conditioning Service in Lake Mary, Florida, and they are trying to sell Air conditioner tune up service. I explained that I am on the national do not call list and asked them to stop calling me. This company does not care about the do not call list, they will call you anyway.
