called didnt leave a message when answered no one there. called them back on diffrent phone. the co is world recovery services. I assume its a collection co.

Calls, leaves no message.  I owe nobody so if a debt collector, it's a prank call.

I get calls from this number frequently, including yesterday and today. They never leave a message and in fact terminate the call after three or four rings before my answering device picks it up. They obviously know they are calling inappropriately when they never leave a message, so I know they really don't care about talking directly with me. I have just added them to my blocked list.

They call daily most times nobody is there and when calling back I got busy signals today they said something when I yelled in phone to stop calling Trying to sell discounted vacations

This company sells septic products. We terminated our relationship with them over a decade ago because we felt their products were overpriced. We continue to receive calls from them (after hours and on weekends!), even though I have repeatedly asked to be removed from their call list.

Although this call was from "The Septic Company", they have gone through a variety of name changes. I suspect, in my dark thoughts, because they are trying to avoid penalties and fines imposed by the FCC for harassing calls to people who are not their customers.
