Thank you all for the information about the Resolution Center! This is pure gold.
I’m having my first orders these days and I just came across a non-responsive buyer. I delivered the order and she asked for a revision but didn’t tell me what she needs changed and the time is ticking. She hasn’t been online at all for a day now but I’m hopeful she’ll log in soon. Eitherwise, I’ll use the Resolution Center to ask for more time.
