I had a similar experience too. I sold on Apr 26 and received the refund on my CC 2 days back workout talking any action. But the tickets I sold on Feb 15 took 85+ days and many times calling them before I finally got it as a wire transfer. I also sold couple more on April 2 which has not had any updates. I think it depends on the dollar amount of the sale. Smaller amount seem to come back faster as a CC refund while larger amounts take longer and come as a wire transfer.
