Question about Paypal cashback voucher Expiry

Does Paypal cashback voucher expire if its refunded by merchant after its expiry date?

My txn on Komparify failed and I got refund as recharge points.

As the paypal voucher expires tomorrow, if I take the refund back to source from komparify, will I be able to use the paypal voucher after tomorrow, in case komparify refund is credited to Paypal after tomorrow?
