Your seller fobbed you off with excuses, and won, because they made you go over the time limit for claiming an item not received, which is 30 days.
Turn now to your payment provider, hopefully not too late there, to start your claim for a refund.
If you wish to buy again on eBay, familiarise yourself with eBay's 30 day MBG, Money Back Guarantee policy, written on every listing , right hand side, just above item specifics, it could save you a lot of money in the future.
