A little googling gives me additional numbers:
360-529-6100, 360-529-6104, 360-529-6105, 360-529-6106, 360-529-6122, 360-529-6136, 360-529-6163, 360-529-6170, 360-529-6175, 360-529-6190, 360-529-6199
www.complaintwire.org has a listing for "Card Member Services" where a few of these numbers were posted, along with many others.
Some reports say Pacifictel was on the caller ID. Others say New A Co was on the caller ID. Some say home security systems, other say consolidate or lower credit card rates/debt. Most say dead air, hang ups or something similar.
Called four times today and it is only 2pm. They don't leave a message. I have removed myself from their do not call list several times and they still call. I have filed a complaint with the do not call list service. If enough people do this, maybe this company will be stopped.
I think that the calling back and pressing 1 will not actually remove you from their list. In fact, most people who posted about the "New A Co" scammers who said they pressed 1 have said they kept receiving the same amount of calls or even started getting more.
I think they use the callback feature of you pressing 1 to register that your number is accurate. They're probably just phishing a bunch of phone numbers and when you call them back and press 1, then they know that there's someone there who is receiving the calls (and they know it isn't some unused or dead phone number), and they will call you more.
I suggest adding any of their numbers they call you from to your contacts and setting them to silent/ no vibrate/ no notifier. Then they call and you don't even notice until you look at your phone, at which point you just click through your missed calls. :)
I've looked online and here is a list of numbers I've compiled that are registered to these scammers:
425-390-8126
253-246-8553
253-246-8552
253-246-8535
253-246-8501
253-246-8510
253-246-8586
253-246-8573
253-246-8543
Generally it's a "253-246-..." #, & they seem to just use variations numbers for the last 4 digits.
***However, upon further research they have multitudes of other numbers listed to them, most of which are invalid numbers, and I'm positive they are "spoofing" their number, which means the number you see on your caller I.D. is fake.
Also, it seems like they call generally in the morning, and it's usually a guy named "Tom" from "New A Co" trying to scam home security. They have attempted a few other scams as well though aside of the home security one including credit rates/debt, and a lot of people say they just get silence. (I also heard some reports say they show up as Pacifictel on caller I.D.)
I've never answered but this is what I've researched. I hope it helps you all. :)
