Just noticed that Ebay charged me twice for Ebay Plus subscription.
The charges were made to my Paypal account and were a week apart (31 July and 6 August). The charge isn't showing in my Ebay account, but its showing on Paypal.
I've been trying to get a refund from Ebay (no luck yet).
Thought I'd post this experience, in case others have also been double charged.
Did you sign up for a free trial twice? Something similar happened to me with Audible and it turned out I had accidentally redeemed a free book on the American store (so couldn't see the charges in my Amazon purchase history) and it started charging me. They were kind enough to cancel it and refund me given I hadn't used any of the credits. Hopefully if that's what happened to you ebay will refund you. You'll probably need to call them and speak to a real human though.
