This question already has an answer here:
Two strangers have sent us money to our paypal account in the past week; the total is almost $700. What kind of a scam is this? I've had no contact with either of these people; the money just appeared as a payment received. I haven't had good customer service from paypal in the past, so I'm thinking if I call them, I'll end up with no help, and wasting an hour or two of my life trying to talk to people who won't and can't do anything. Have you heard of anything like this?
