The Caller ID says Outreach Association.  I get close to 5 to 6 calls a day on an average.

Starting early in 2010, I began getting 5 calls a day from 412-773-8558.  No message is left on my voice mail.

Numerous calls, but they never leave a message.  As far as I'm concerned, they can dial a tree.  I'm  thinking about getting rid of my phone , because AT & T does not help with these annoying calls.

Got a call from this number as well, it is a fundraising thing. I asked to be removed but still get calls.

I've seen numbers from 412-773-8554 allll the way to -8582 (so far). Have blocked all of them - no calls since. We'll see.

Same here - they call ALL the time around 6 p.m. during the week, and sometimes on the weekends. Never leave a message. When I finally took the call, the "representative" wanted me to renew my annual Sierra Club membership (actually increase it) - asked for my email address (which they already have) and my credit card information (which they should have on file). Did not give anything to them. When I told him I preferred to call back with that information, he gave me a phone number and assured me that "an organization that was trying to scam someone would not give a call-back number." Who said anything about SCAMMING? (HE did!)

A search online yielded no matching number for the Sierra Club or any operations out of the PIttsburgh area for either of the numbers he gave me.

If this really is the Sierra Club, or a call service acting on their behalf - they need to get their act together!! If it's not - and I'm guessing it's not - they need to know about these calls that are souring people on Sierra Club!

No message

Just got a call from this number; caller ID said Outreach Associates. When I answered, there was a pause and then an automated voice said to hold for the next available agent. Like that would ever happen. A Google search on Outreach Associates turned up info from 2004, which linked the organization to Direct Marketing Advantage, 2100 Wharton Street, Suite 510Pittsburgh, PA 15203. 412-381-2300. info@dam.com

These calls are from the Sierra Club.

They have tried to contact me three days in a row roughly around 6:00 pm.  Never leave a VME.  When I did answer the third call, no one said anything and hung up.

This number calls 2x per day.  It is "Donor Services" or some such, and when I call back, it tells me to leave my name and phone number.  Yeah right !!!  What a pile of dookey.  How can we get it stopped?

They gave been calling me for weeks!  They started off using 412-773-8566, then changed the last 4 numbers to 8570, then 8574, and now 8558.  Every time I block them, they change the number and dial again!  I would love to find out what charity, org, party, group, they represent so I can send money to an opposing group.  Meanwhile, I shall continue to block every number they come up with.

they just called me, no message.

did not leave a message, when I called back I got a recorded message saying I had reached the donor services center.  (for what?)

They keep calling. Do not leave a message in voicemail. Called three times in two hours on a Sunday afternnon.

We've asked to be put on their no-call-list, but they keep calling anyway.

412-773-8558  They leave no message.

ditto to the abov.  i heard talking in the background and had to hold on for about one minute in order to delete the message.
