(331) 200-8575Dangerous

It's been 3 years since this number was last posted here on 800 Notes, but they seem to be back. Caller ID said "Illegal Scam," which is, of course, redundant. We did not pick up, but I have to wonder how many others will answer just out of idle curiosity as to why a scammer would choose such an ID.

(331) 258-2057Dangerous

I get them on both land line and cell phone. Since it looks like we could see more "stimulus" money, the scammers and bottom feeders are out wanting as much as they can get out of you. Even though Congress hasn't voted on it or the maniac in the Oval Office hasn't signed the bill yet.

(331) 302-2512Unknown

Said he was from Cosmo, he sounded professional so I answered some of them but he started asking more detailed questions and I wouldn't answer those. He concluded the call shortly after that

(331) 302-2512Dangerous

Ewwww. It started out super normal and totally something I read in cosmo mags.. but then his voice got softer and softer and it was just strange. I answered majority of the questions (embarrassingly enough) and then googled the number afterwards.

(331) 302-2512Unknown

This just happened to me too... I was the most awkward, it seemed legit, got off the phone told me fiancé about it, even said that even if he was a creep I was probably the lamest survey. The guy even asked me at the end if there was anyone else I knew that would be interested in the survey that was more adventurous.... that’s when I knew. Next time I know.

(331) 256-2546Unknown

Recieved an email to my business asking to buy "for SSDs" stunk of a scam, oh hye look it's from GuidryDouglaspaulJr@outlook.com.. imagine that!

(331) 256-2546Dangerous

Same scam here:Hi Sir/MadamMy name is Mr. Douglas, I would like to order for SSD.ThanksIt's from GuidryDouglaspaulJr@outlook.com

(331) 240-3131Neutral

Threaten to kill me

(331) 302-2512Dangerous

Dirty old man looking for a rise. Says he is with Cosmo magazine but as soon as you don’t answer he just says thank you & hangs up.
