Ok, so what you are saying is that you made a mistake? Now instead of directing your frustration over that mistake into constructive efforts to make sure the mistake doesn't happen again, it appears as though you are directing that energy into anger over the eBay platform? Huh?
There is a VERY good reason why a seller will not change an address after the sale. I'll give you an example. Say you are selling a $150 watch, I buy it and pay for it through eBay. So whatever address I have on the checkout screen is what comes through to you as the "ship to" address. But I send you an email afterwards and say, "Oh, I forgot I was helping my sick grandmother of 95 get through COVID and forget to change my address back when I got home, please ship the item to me at: __________" So you being a good human being and wanting to help, especially a kind person helping out their relative, changes the shipping label and sends the watch to the address in the email. You feel pretty good about yourself because you helped another person out who made a mistake. Unfortunately, the tracking shows the item as "delivered" but the buyer files a case for Item Not Received! You jump up and down, and state that the tracking shows "delivered!" But the buyer goes to the USPS and gets a letter from them that states the address of where the package was delivered is different from the address on the order! What you didn't know is the address on the order was the buyer's uncle who lives across town and the address they sent you by email was indeed their address. So you scream and yell to eBay, but they point out that any seller is required to deliver the item to the address on the order to be protected against INR cases! So by 'being a nice person" you violated eBay policies and you got scammed. I get to keep the watch and I get a FULL refund from you - now you have experienced a Maximum Loss: lost the watch AND lost the money, eBay fees, shipping costs, etc.
So now do you see why any seller that has their wits will not change the address after the sale just to 'help you out?" Pushing the point too much could make you look like a scammer and end you up on their "Best Buddies List."
So probably not how you see things and not what you wish to hear, but just wanted to share that view point for you to consider.
