Hi, thanks for reaching out. What Microsoft account email are you using for OneDrive?
Please check your Microsoft account at account.microsoft.com to confirm your subscription and storage. Make sure your device time and internet connection are correct, then open OneDrive settings and sign in again. Microsoft does not delete photos unless the account is inactive for two years or storage stays over the limit for a long period. For your 1500 won payment and refund request, review your Order History and contact Microsoft Support through the official site if you need help with the charge.
