Crazy IDT Carmel Calls

I've been getting calls from IDT Carmel for about a month now. They keep calling asking for Gary Wray. Nobody of that name lives at my address, only me and my mother. However, in the phone book there is the name "G. Wray" listed at our address. This was Gertrude Wray, my grandmother that died back in 1995 while in her late 70's. There is no one else in the family by that name. She did not having any outstanding debts and we don't either. We left her listing in the phone book so distant relatives could find us easily.

We keep explaining this to them but they refuse to stop calling. They also won't tell us what the debt consists of, except that we better tell Gary to call them and pay it. Its annoying because they are calling everyday and when we are not home, they leave long messages on the voicemail. I have their 1-800 number and have called them directly to explain the situation but they just hang up on us.

We are on both federal and state do not call lists. I've filed complaints on them to both (even though they may be exempt being debt collectors?). Often the person who calls has called us before (a few of them have distinguishable voices) and acts like we're either stupid or trying to hide whoever they are looking for.

Any ideas on how I should proceed? I'm ready to contact my lawyer for harassment but would like to try my other options first.
