who is this ?

Called 3 times in 10 minutes.  No message left.

i called it back - she said they were an answering svc for various companies.  wouldn't give me any more details.

Saw that I had two missed calls. No message left. When I called back, all I heard was "thank you for calling, please hold." No company name. It sounded like the guys said something about an answering service. He asked me for my account number and I told him I got two calls but no message. He then said he had no clue who called me then and hung up.

Got two more calls from them. No message.
