I rec'd a call just now.  Caller I.D. read "Gresham OR"  They left no message.  So annoying!

I just received a call from this number. Answered it as normal, LT. __________ , GD Security, no response from the other end. Called it back and didn't even even ring.

I've gotten calls on a monthly-bimonthly rate from this number stating that it is a data compiler for google.

I also called it back today for the first time getting a message that it is a dnd registry going to contact google to see if they own the number or are connected to that number.

Rec'd a call just now from the number.

I keep getting calls from this #.  I'm never home when they call, however, I am on the do not call list & I want them to stop!!

I called them back and an automated message said to press1 to enter my ten digit number so they can stop calls from them. i don't trust it. I think if i put my number down they might just sale it or something cuz even the automated message guy sounded shady.

Just got a call from this number from an automated service regarding "card services" asking if I was interested in a reduced rate on my credit. When I called the number back, it said it was the "Automated Do Not Call Registry" and prompted me to enter my phone number.

Just got a call from this number on the cell; didn't answer and they left no message.  So much for the "Do not call List"

I have received several calls on my cell phone from this number saying I can reduce my credit card interest rate.  I was only given one option to respond to the recorded message.  I hit "1" and got a live operator asking for my credit card number.  I told him to please take my number off their calling list and was immediately hung up on.  This same thing has happened three different times.  And I thought I was on a nation-wide no calling list.  What can be done to spot this?

got called from here recently.  how do i stop them?

Just got a call from this number on my cell - refused the call, and checked the internet for any responses or connections with this number - when you're unsure don't answer and let them leave a message - then you have info to call your State Attorney General's Office for phishing abuse calls.

gat a call and a hang up twice today!  This is my cell they call and should not be doing so.  Probably someone trying to sell me somethin.

I also received a call from this number about 20 minutes ago.  I did not answer and good thing I didn't!

I just got this call too, said it was from "card services" . Was a message offering a reduced rate on a card, and the operator started asking me for some credit and personal info. I asked what card this was in reference too, amd she asked for more info, so I said I couldn't give her any personal information unless I knew who was calling, or what card it was in reference to, and she smugly said "bye bye!" and hung up on me.  Sounds like a phishing call to me.

Was called by this number about a half hour ago- attempted to call it back and received a busy signal.
