They call all the time. When you call the number it says not in service. When they wait long enough for the answering machine to record the call; no message is left. It is just an obnoxious ''ding'' sound.
Called 4 times in the last two days, no messages. I'm on the DNC list. Do not do business with outfits that ignore the DNC list. They're dishonest. And annoying as hell.
