Called it back after missing it only to find out they are a debt collector.

They sound like they are from India.
I spoke to them and they say the are from a collections Agency called Allied Interstate.  There is nothing good about them in the internet.  Just make sure she does owe that money before you pay them anything if what they are calling her for is to collect from her.

Yes, sounds like he is from South Asia and keeps asking for my wife.  Refuses to tell me what he is calling for or about. Called yesterday but hung up.
