They call every day at noon (or just before noon), they never leave a message, if I answer the phone, they hang up. Reported to FTC since we're on no-call registry.
I think she said it was Delta Air Conditioning, it was very bad connection at first. They call and hang up. I called them, reported the hang up calls, they asked if I wanted placed on their Do Not Call List ... Yes. PLEASE. They said I will get no more calls from them.
They call at least 3 times a day every day for the last 2 weeks.
