I have NO ex-spouse, NO outstanding debts. Have been getting calls on my cellphone every other day, in the morning for the past week. If I answer, i just hear "boiler-room" noises in the background then it hangs up.
I just purchased a new phone and got a new phone number, this was one of the first calls I received so knowing it wasn't anyone for me I didn't answer it. It calls me at least twice a day. You would think after about the 15th phone call they would give up.
