When a payment intent is created, GCash immediately shows the deduction as an authorization hold - this secures the funds but doesn't actually charge you yet. Even though it appears deducted in your GCash wallet, it's just temporarily held.
Since your payment intent was cancelled before being captured, that authorization gets voided and the funds will be automatically released back to your GCash account within 7 days.
If your receipt doesn't contain a 6-digit QRPh invoice number, the balance will typically be credited back to your GCash wallet within 24 hours.
So yes, you'll get your money back - it's just the timing that varies depending on whether it was a standard authorization void (up to 7 days) or a QRPh payment issue (within 24 hours).
