ofc! for the ones involving usd, reach out to th staff and send proof of them paying + chargeback on each oc, the psa links, etc. it should be plenty enough atp for them to get the ocs transferred back to you! this applies to everyone impacted as well who sold them an oc and got charged back. i wish you luck hun!! 

also for the one that was traded away but you sold them originally to sheller, contact the new owner, you never know, most people will feel horrible and give the oc back to the rightful owner!
