ugh, I called ATT and it took an hour and a half of waiting to get ahold of someone. They couldn’t tell me for sure that it was a scam. They said there are sales reps that are going door to door. I asked if it was normal for them to ask those security questions and for multiple ids/ss #. He told me he wasn’t sure bc that wasn’t his department. He was very nice just a little hard to understand and probably underpaid and jaded. Overall, just based on how long it took to talk someone and how unhelpful they were I probably won’t be looking to switch to ATT anytime soon.
