this # left a voice message on my phone. someone was breathing really deeply then just hung up. i don't owe anybody money, and i don't know anybody in maryland. we're on the "no call" list....in fact, we just signed up for THAT two days ago. WEIRD!!
My phone received a call from 301-575-9350 on a Saturday morning (2007-09-27). Caller ID could not identify them. They didn't leave a message. Have no idea who they are, what they want. I don't owe any money, don't have any outstanding bills, and my phone num is unlisted (it has never been listed).
Also rcvd call from the above number. Got the impression they were some type of research group. Woman asked me about my visit to a local hospital on 10/29; I was at that hospital several months ago, but not on 10/29. Woman replied apparently they had made a mistake and apologized.
When I returned a phone call to this number the message said that they were calling to take a survey and ask a few questions about a recent doctor visit someone in the household had. They asked me to rate my satisfaction of the doctors performance on a 1-10 scale, their nurses and the overall satisfaction with the visit.
