OMG,,,they have called us for months. We have tried everything to find who they are, what they want and the one time my husband did speak to someone he politely told him we werent interested and a few hours later ,here we go again. I tried blocking , the number was then switched and they used different numbers, they call about 4 times a day, even on the weekends and mostly when we answer you hear silence and a few seconds later a dial tone. Maybe Whoever they pay to make the calls have found a way to let a machine do all the work calling people and they just take it easy.
US Security. Literally dozens of calls. When you answer, no one on the line. If you say nothing and wait, nothing happens. If you let it roll to voice mail, no message is left. Extremely irritating.
