Just received a call but they left no message. When I called back I got a fast busy signal..probably a telemarketer of some sort.

this is a call about ads... my phone number is unlisted, so how did these people get my phone number.. and i want this people to stop calling my number to sell me something!

They are robo dialing.  We are all getting calls in this house and our phone number digits are close together.  In a related note, is anyone else getting these calls also getting phone calls from (360)-460-xxxx numbers where you are blasted in the ear with a boat horn on a regular basis?

This is the voicemail that was left for me from this number (google voice translation):

"For an all inclusive cruise to Nassau, Bahamas in exchange for your answers to 10 questions and then use of public opinion poll. The process is automated, just press the keys on your telephone keypad for your [***], Hi Will Receive 2 Free boarding passes for an all inclusive cruise to Nassau, Bahamas. When you're finished this process only takes a bit, press 1 to start the automated survey and receive 2 complimentary cruise passes. Don't miss the vote press one. Now we're going to be removed on."

When I return the call I get a busy signal.  

This is the 6th call in 3 months

I received a call this morning from 360-460-5964.  When I didn't answer they left a voicemail message telling me about the cruise offering exchange for answering a survey.  Outside of family no-one knows my number.  I wish there was a way to build a block-list on my cell phone.  As it is, I assign it a no-ringer, but that still leaves the voice message issue.
