Yeah they have called me 30 times in the past 3 weeks, usually hang up or ask for a person that does not live here. When I ask them to stop calleing me and that they have been calling me 3 times a day they just hang up. I would suggest an air horn or a high pitch whistle the next time they call.
That number has been calling me for the last few weeks 3-4 times per day and hanging up when anyone answers. Very annoying and there is nothing we can do to stop them from calling.
