Who called from 5712610051

Calls came in 2-3 times per day between 8 am and as late as 9:30 pm.  When I used to answer, I would say hello several times, to no answer from whoever was calling.  Then I just started ignoring the calls.  They never left a voicemail, but they did fill up my voicemail with 3 minutes of dead air per message.  This was annoying enough that I added this number to my blocked numbers list with Verizon.

I receive calls regularly from this number since I purchased my new cell phone in November 2009.  They claim to be a pharmacy in India.  They know my name.  They told me that I am a client.  Not true.  I have never ordered anything from them.

571-261-0051, no one answers then they disconnect, happens around every 10 to 30 days. I am on the do not call list.
