History shows 2 purchased items. The only way that can happen is commit to buy , so you did ,whether you believe so or not.
Only seller can cancel a listing and they do not have to. Can file an unpaid dispute and if you do not , ebay assigns a strike to your account. 2 strikes from different sellers and buying is almost impossible for 12 months as most sellers have 2 strike members blocked.
Be sure before committing.
