They called me daily without leaving a message. When I called them back the employee claimed they are calling regarding a business matter. It must be shady or not very important considering they won't leave a message. They wouldn't give me any more information since I refused to give them my name.
I'm having the same issue. I actually picked the phone up once and the woman who answered claimed it was a "business matter". I told her she had to put it in writing because I had a someone who dealt with any business matters. She got rude with me, so I hung up. Now they call repeatedly throughout the day and won't leave a message. If this is, indeed, a debt collector, since I told her all contact must be in writing, I believe she's violating the law.
