I received my first negative feedback today.
Here is the story.
I readily admit I made an error and send the incorrect coin to the buyer. I send an e-mail to the buyer stating the following
"I believe I sent you the incorrect Faustina. When it arrives please check quickly and if you could ship it back regular mail it would be greatly appreciated. Please let me know the cost of shipping and I will reimburse you over paypal."
I do not hear from him for a week and receive this message
"I received a package from you containing 2 coins. One seems to be an ae as Faustina, the other I do not know except that it is smaller and the emperor has a crown. Please send me a prepaid envelope and my sestertius and I will send to you what you sent me in error.After all, you made the error, not me and I sent you the proper payment. Please respond timelt"
I respond within 20 minutes saying:
"I already sent the Sestertius so unfortunately I cannot add the prepaid envelope to the package. What I can do however is refund the purchase which should cover the cost of shipping back and then some. I apologize again for the mix up. I will send you the money as soon as possible(most likely later tonight). I am just away from my main computer at the moment and don't want to refund it on my phone."
I never heard a response from him and then received the negative feedback today after I had refunded the money. The coin I resent should arrive early next week.
So, I have two questions: How do I block this buyer permanently and is there a way to respond to the negative feedback to make a note for people looking at my account?
