Claim they're from Florida Water Heating. Have received at least 10 calls in the last few days. I picked up today and when I told the girl the number belong to Sun Products in Connecticut she said oh there must be a problem with your caller ID.  We're in Florida. Then she asked me do you live in _______ and she named my city.  I told her no I'm in Connecticut.  She said oh I'm sorry we must have a wrong number.
