I deal with Paypal all the time, as many of us do. First thing I would do is see if it is a scam. Forward the original message to:
SPOOF@PAYPAL.COM After their response, you will know. Next thing I would think, the buyer stopped payment to you, & I assume received the goods, thus a person to be reported to Paypal if this is the case so you can be reimbursed. I truly think it is a SPAM, & be careful what info you give them...Do the SPOOF thing first. Hope this helps. Craig SS#1256
