Alright finally got some information on these guys
They go by Travel Trivia, and (edit 5/27) depending on how you view these posts, you might say they impersonate major airlines. It’s a bit iffy, but some of their posts on Reddit could be interpreted as such (end edit)
https://www.reddit.com/user/traveltriviaonline/ This reddit user spammed reddit claiming to be major airlines using the same number in the email they sent me.
Things seem to connect to this thread, 877-464-9297 Flight Reservations however they do not seem to be related to the original number and center posted.
https://listings.usa247.info/explore/united-states/new-jersey/632444-travel-trivia.htm gives traveltriviaonline.com and an address of 3910 Park Ave STE 6, Edison NJ 08820. Website gives (877) 770-0160
As mentioned before I did get an email from them. The @ is [email protected]
I am being spammed called rn, new numbers is (281) 715-0905 and (469) 447-8517
