OP, to be honest, I don't believe in this world some people demand thanks or anything else for the kindness he has given.
give kindness to everyone, without that person knowing it. that's the real goodness.

I do not expect you to ask for a refund. to be honest it is bad manners. unless the person concerned borrows from you. but this case is different from your understanding.

I will only pray for you, I hope you are happy with the much money you have. but what happened to yahoo62278 could happen to you. Take care of your health. have a nice day.
