I sell digital products online. Every other day, Paypal opens a case for review and reverses the payment to the buyers. When the first time, I received this type of email, I send all the details to Paypal with Transaction details and the proof that the file is accessed by the buyer.But still they reversed the payment to the buyer.lso, atfirst I thought the Case is brought out by the buyers who might not have liked the product, but actually when I read it thoroughly I came to know that the case is actually been opened by Paypal for investigation. How do I respond to this type of investigation cases.
