Case opened not by me

[sweetseats10]

Does a case automatically get opened if a seller doesn’t upload tracking info?  I purchased an item Friday and the next day a case was opened on my behalf requesting a tracking number.  Then the seller uploaded an old tracking number showing an item delivered.  0 feedback seller and the item I bought was well below market.  Is this how fraudsters operate?

in addition I’ve received three emails from customerhelp_ca@ebay.com with chat transcripts attached.  I don’t dare open the attachment.
