Received a call from this number.  The only sound I got was "Good Bye", then the phone disconnected.  When I tried the number, the person at extension 706 was on the phone.  Right.

The calls you are getting are most certainly farming for viable numbers to spam about time shares.  Here;s my experience:

Sharee with getaway vacation dreams 8886056586
called my house at 350 pm on 3/9/2011 with an unsolicited call regarding a vacation offer
they wished me to extend an offer they had made me (of which i have no recollection).
I am on the national do not call list.
I told her that i would not do business over the phone - she offered an internet business site - I told her that I did not trust them due to the rampant fraud in the news so often and that if they wished to do business with me they would need to do so via usps - where lying constitutes a federal crime.
She asked me to hold while she got a supervisor.  He praised his worker then I told him the same - his reply was:
"and you will not eat green eggs and ham either will you (vulgar word)."
I find that this call does in fact constitute harassment as defined in the Ga Secretary of State's description and am reporting it as such.  Although he did not threaten physical violence, his crude language over an unsolicited call both violates the DNC registry guidelines and my state's laws, but also constitutes slander.
I called the number back and left a message for the owners of the business requesting a formal apology from this employee, and from the business owner.  Furthermore I am reporting them to the local BBB, my SoS, and the DNC registry as a violation.

Unwanted calls; told them to take me off their list, they keep calling.

How to block 1-888-605-6586

I got a call from this number and got an automated "Goodbye" - Lately I've been getting a lot of spam telemarketer calls. What a piece of s*** system these f**** must have.

No answer when picked up.

Received phone call, did not pick up.  No message left on my machine.

Caller did respond when I answered the phone.  He asked for my father-in-law, who died over four years ago.  I asked what the call was about and the caller hung up.

Almost certainly a telemarketer.

Often we find these calls are about time share condos.

Just received a call from this number, since it was an unrecognized number I answered with just, "hello, hello, hello" to which I heard nothing but static.

"Goodbye, " was then announced by a voice.

Thank you for waisting my cell phone minutes, I will be sending the caller an invoice for 12 seconds of consulting time, plus the minimum service charge of an hour of work, in addition to the cost per minute for the call, which I have here on the phone as 12 seconds. That comes to around Three Hundred Forty Six Dollars and 00/100 cents.

I called the number back and it was someone asking us about our unused timeshare points (?)  I said no thank you and hung up.

Got a call from this number last night at 7:40.  I said Hello 3 times.  All I got in return was an automated 'Good Bye'.  Crazy.  Probably a debt collector still looking for my husband's ex-wife.

Boy, these people are out in force the last few days. Call on the home phone from this number. Wife picked up. No one said anything on the other end.

I get phone calls from this number all the time. They don't leave a message, no one ever answers and when I call them back there is no answer and "their mailbox is full". How do you stop these scum bags?
