Hi @benowen,
Great question. First, we will want to ensure the emails you received are truly from PayPal. Here is how you can spot fake emails and how you can report them from our Help Center.
If a customer sent a payment, even if it may not be available immediately, it will reflect within your PayPal balance. If your balance is showing 0.00, this means the payment was not legitimate or the invoice request is not complete. We advise you to not ship your product until you see money within your PayPal balance on our official site. We would not hide payments from you.
If you are showing a balance, but it is not yet available, these are the typical reasons why. If the money is pending, and you would like the funds to be released sooner, we recommend you to provide tracking information to PayPal and the buyer.
I hope this helps!
