If I make a purchase from 15/05/2023 to 28/5/2023 (23:59), but my transaction is cleared after 28/5/2023, will I earn 10% of the value of my purchase/s in my payzy wallet from www.cosmosport.gr?

Of course 10% of the value of your purchase(s) will be paid to your payzy wallet, provided that the payment was made with your virtual/physical payzy card by 28/05/2023, irrespective of whether the transaction is cleared in the next business days. 10% of the purchase(s) paid for with your payzy card will be credited to your payzy wallet fifteen (15) days from the date of purchase and provided that clearance of the transaction you carried out with your virtual/physical debit payzy card has been completed.
