I'm sorry to hear about your mother getting scammed. I've had similar experiences. The scammers probably don't work inside a PayPal call center. They probably contact the victim after some delay, and unless you're certain that the person you spoke to on the official number was the same person who called you back, it's probably someone else. The other possibility being that the number you thought was official wasn't right? At the time of writing, I'm seeing it as 888-221-1161 and you can probably verify it from the call history on her phone. But if the rep was the same one who scammed you, then it should be easy for PayPal to identify her since they record all of the calls. Of course, they probably won't volunteer her name, but if multiple people complain about being scammed by her, they'll at least investigate.
