The sale was made outside of Audiogon. The seller would have to cancel the listing to do that. Feedback can not be exchanged on an item that is not listed! Audiogon never received the selling fee. They are not running a business for free!
Leaving feedback
How does one leave feedback if you paid seller by wire transfer outside of agon site? I didn't officially enter offer and seller didn't officially accept as we were texting back n forth. Deal is done and everyone is happy.
