How do I contact seller if listing was removed from ebay

[JumpSteady]

I did buy it now on a disposable e-cigarette and paid through paypal.  The listing was removed by ebay for viiolation of terms and no longer appears in my won in my ebay.  If I goto paypal I can see where i sent payment, and under name/email it shows their name, but this is neither an email address or an ebay id,  If I click details it says This transaction will appear on your bill as "PAYPAL" "xxxxxxxxxxxxxx)  But this is also neither an email adress or ebay id.  If I click on item title from paypal it just says This listing (xxxxxxxxxxx) has been removed, or this item is not available.

All I want to do is contact seller and ask if they sent it, how can I get their ebay username or email adress from the paypal transaction?

Never mind.  I figured it out.  I realized there was a reason why I had saved every email from ebay and paypal in a special folder in my yahoo mail for the past 10 years.  I just went to the Receipt for your PayPal payment to XXXXXXXXXX message in my email, and there is the sellers ebay name and email address.

It's sad though, that if I had permanently deleted that message, I would no longer have access to the ebay id or email address of a person I had completed a transaction with on ebay and sent money to via paypal.
