Sorry to hear that blessed2. It still may be worth calling any business nearby last location reported. A good hearted person may have found it and gave it to lost and found. It’ll be much cheaper to pay for shipping it to you than replacement. A single airpod pro replacement is 90 dollars. You can open a case with support to get the replacement here:

If you prefer to just buy a new set outright, IMHO hold out until late September. Odds are good AirPods Pro 2 will be introduced. While It’ll be FULL price, it is likely this new generation will be a substantial upgrade. At that time you can probably sell your existing case for 40$ (maybe less, maybe more).
Best of luck…
