My wallet address changes after each transaction, if i am to get a refund from escrow how does it go back to my wallet? Does each of my old receiving addresses still route the refund back to my wallet? Please help as its been nearly a week now since my refund was supposed to have been sent-yet nothing has been received. Appreciate the knowledge/ direction of anyone that may be able to shed some light on the matter.
To get a refund provide the sender with another address from the receive tab. That's how bitcoin works. You can't guarantee that the "from" address of a transaction belongs to the sender so anyone who's sending money back to it is doing things incorrectly.
Having said that if they did send the refund to one of your old addresses you would still have received it. Most likely they didn't send any refund.
