Same thing - rings once or twice to our biz line, then hangs up.
Lots of calls over a few days, then none for weeks, then it starts up again.
Caller ID says "Insurance Services", similar numbers = 973-360-2026 shows as "Kushner Comp".
They are calling our incoming 888 number - so WE get to pay for these annoying, unwanted and useless calls. We DO NOT have any other prior contact.
Complaints filed. Why can't the FCC stop these jerks ???
