Maybe I'm not getting something here.
I've been using a PP debit card for years, and there's never any need to pay any balance (therefore no late charges), because it just debits from your PP account in real-time. Your card spending limit is how much money you have in your PP account.
You use the PP debit card, and the amount is taken primarily from your PP balance, even if you have a bank account linked.
eBay and Paypal are so tightly linked I often mix them up, I edited.
eBay bought PP a long time ago but they're now separate companies again.
The store let me order and charge me then they told me that they didn't do the ship to store option so I asked for refund. So I paid it with my paypal and its still pending they said I have to fax them some papers for some odd reason. Will never use paypal again and I still have not received refund.
That's not PP's fault. The store has to initiate the refund. If the store does not initiate a refund, PP won't credit your account.
Now, you can call PP and contest/dispute the charges of the store. Tell them you cancelled the order with the store but the store has not refunded your payment. PP will issue you a provisional refund while they investigate the claim.
