A side question for all people supporting no refunds. If someone received a transaction by wrong should he give it back to its owner or keep it? What do you do in daily life? If you received an upfront paid delivery while it was for your neighbor would you eat it because the delivery guy gave it to you by wrong while you know who owns it? I saw some Muslim comments that should be knowing this (Rasulullah SAW also reminded Muslims that indebted persons are tied to the repayment of their debts. An indebted person must settle his debts in his lifetime, because if he dies while still in debt, then his soul will be suspended until his debts are settled) and this applies for this situation.
