I know there's been a bunch of threads on this already (like https://forums.macrumors.com/threads/71706/), but like, I still can't believe it, and if I bring those threads back to life, nobody'll pay attention to it. I also am aware that there are a LOT of threads on Google about people from Apple calling, but none about buying stuff from said people. So here goes.
Some lady from Apple apparently called my cellphone from a number that originates from Northern California (916 399 7992) and it was bizarre (plus I called that number back, and it's a prerecorded message of someone saying stuff about Apple). She called me asking me if everything was alright with my iBook, et cetera. So I tell her about all the little quirks that make my iBook my iBook. Then it turns out she was calling me about a laptop I bought for a friend with my edu discount. So we started talking about the iBook that's actually in my possession, and turns out that I have about 20 days left to get AppleCare on my iBook G4 if i wanted to. So I told her I'd go and get it at the store, but she tells me she can offer it at a lower price ($189 as opposed to the $249 in store/online) because she works at Apple Corporate.
So she wants CC/debit card info over the phone, but I have no idea she's who she claims to be. Especially because I don't remember putting my cellphone number on any Apple registration forms, although my friend might have done that when she registered the iBook I helped her buy. But that friend's not there, so I don't know.
What do I do?
