Scammed and can't open a case
As explained by others you where scammed but it had nothing to do with eBay or Paypal.
You paid by Paypal which is one of safe payment methods you can use and a seller has to accept if they state it in their listing.
Then you choose to cancel the safe payment method and pay by an unsafe method because the seller claims a fault with their PP account.
What you should have done is notify the seller that they can either claim the payment,reclaim the money and tell them to fix the PP account,(you could then have repaid them once the account was fixed).
In this instance you just wouldn't have heard from them again,(except for them trying to get you to pay by bank deposit),X-(
Never,ever pay a stranger by bank deposit unless you can afford to lose that money.
A number of these accounts are hijacked accounts that list high priced items for prices that are way below their true value,(which should be a warning to buyers to start with).
If it looks to good to be true,it generally is).X-(
