It's been a long while since I used that feature here (to get contact information):
https://www.ebay.ca/sch/ebayadvsearch?_sofindtype=9
But when I try it, it says "This feature has been deprecated"
How can I contact the seller I bought from now? He just ignores the 3 messages I sent. Maybe - just maybe - he would answer a phone call. At least, it's worth a try.
I'm trying to resolve the situation like a grown up before leaving appropriate feedback, because I want to give him the benefit of the doubt, but he is acting like a child....
