received a call twice from this number, left no voice message

They have been calling repeatedly for two nights.  I say Hello? and they don't say anything.  So the 4th time they called, I didn't say anything and finally a lady said something, so I said, "You guys have called me 4 times and you don't say anything!  What company are you from?" and I couldn't understand her but then she asked if I would take part in a survey. I declined and hung up.  They called me AGAIN 10 seconds later.  Annoying!

They call me every hour.. saying they are taking a poll.. I told them take.me.off the list. They said they can't.. it applies only to telemarketers selling something. BS.. they are really annoying me.

They have been calling for 4-5 times per day for the past two days, even at night. left no voice message.

They have called me two night in a row 5 times between 9pm and 12am. Really piss me off, who the hell calls that late. No answer and no voice mail.
