It seems likes eBay policy wants you to wait 4 days to open a case then wants you to wait another 4 days for payment?
Yep. Those are the rules for an Unpaid Item case.
There are different rules for a Cancellation Request.
What would you do if you relisted, and the original bidder AND the new bidder both paid?
Think about that, as you read the following:
If you want your Final Value Fees refunded, and the ability to make a Second Chance Offer, or relist correctly, you must do one of the following:
1. Complete the Unpaid Item process (usually preferred)
or
2. Convince the buyer to agree to a Cancellation Request,
Both options are available in the eBay Resolution Center
Here is a comparison of the timelines, pros, and cons of filing an Unpaid Item (UPI) report versus a Cancellation Request (CR)

Also consider putting the bad bidder on your Blocked Bidders List. (Stop back here for more information if you need to learn how to do that ... in fact, it would be courteous if you let us know you read any of the answers to your question).
