Can I reopen a closed case? The seller sent me tracking number and said he would ship and so I closed it but the package hasn't even been shipped. If I can't reopen it, can paypal still help me at all?
No. It was your choice to accept a promise as the final solution and then close the case.
The seller was very smart. This was an important learning experience to let you know you need to be much more knowledgable and smart about PayPal policies so scammers don't take advantage of your inexperience.
