attinternetservice.com - legitimate?
We just moved and are signing up for AT&T Fiber. I had some questions about signing up/installation and searching for a support number on Google found a "New Customer" number on attinternetservice.com. It seemed legit - I called the number and he started setting me up. Everything seemed fine, he asked for some address information and my social. I gave it to him, but decided to back out before completing set up. He was pushy trying to have me complete setup, but I backed out.
I'm slightly concerned it wasn't a legitimate reseller and I just gave out some personal information to some scammers. I think the more likely scenario is that they are legitimate, but essentially act as a middleman (reseller) vs. going directly through AT&T.
Should I be concerned about giving out that personal information via phone?
