If you have waited for 2 months for a reply or a refund from the seller,  then you have unfortunately,  waited too long,  and exceeded the time you have with eBay to claim for a full refund.

Never listen to a seller's excuses when this happens just follow eBay's 30 day MBG Money Back Guarantee policy this is written on every listing,  and I've included a link below explaining the process.  You open a case and escalate on day 4 if you're not refunded before hand.

  As said,  this time has passed so you need to now turn to your payment provider for help with your refund.

Don't allow this happen again, read about eBay's MBG here.
