Purchased item has been removed on eBay and not received

[doris300763]

I purchased a magazine on eBay 2 days ago.  Yesterday I received an email from the seller to say the item was slightly different in size to what I thought I'd purchased and Was I happy to go ahead.  I tried to reply yes, but the email also stated that it was over 90 days old and therefore I wasn't allowed to reply so there was no way I could respond.  Since then, my purchase history has been removed from eBay and there is no way for me to contact the seller.

ebay doesn't give me any means to contact the seller as it's now not listed on the site as a purchase.

in addition, PayPal has already paid the money to the seller and it tells me to contact the seller if there's a problem through ebay, which I can't as the purchase history has been removed.  

can anyone advise what to do next?  Thankyou
