got calls

They've only called me twice and have not left a message either time.  It is a company called Rikenbacher Group or something like that.  They do collections out of California from a reverse look-up I did.

I get calls which say that I have urgent business with them. But if I return it I hear the name of a company I am not familiar with and can not for sure make out. Sounds something like "inbarker". I am prompted to enter my account number. Have not been able to get a real person on the line.

These guys keep on calling and leaving recorded messages. Interuupts all day. Told them I am not the right person; but, their "broken" record keeps on ringing.
