I went ahead and filed a claim on the 5th because I felt I have already given Jors plenty of time to make things right. On the 15th, Paypal decided the case in my favor and has refunded me my money.
June 8th, 2020: Jors Tweeted that he was offering bust sketches, and that the proceeds would go to Reclaim the Block. The same day, I reached out to Jors to have one of my characters drawn. Jors was asking for $40, but I sent him an extra $15 for a total of $55 through Paypal. Jors told me that he expected to complete commissions within a week. He stated that, once he had completed all the commissions, he would post the donation receipt.
June 9th: Jors posted a completed bust commission for another user.
June 10th-August 19th: Jors is inactive on Twitter.
August 20th: Jors posted two more busts on his timeline. He did not specify that these were donation commission sketches, but they appeared to be the same style. I assumed that it meant that he would soon finish the other busts, including my own.
August 21st-September 20th: Jors was actively posting on Twitter. I did not receive any messages concerning commission progress. After September 20th, Jors has not posted on Twitter.
September 27th: I contacted him through Twitter again to see if he was making any progress on the donation commissions. I did not receive a response.
October 17th: I message Jors again, letting him know that the end of the chargeback period is December 5th. I told him I hoped to resolve the situation within the next month.
November 2nd: Jors did not acknowledge my last message despite having over two weeks to do so. Initially, I intended to wait until December 5th before opening a dispute. However, his lack of response suggests to me that it is unlikely that he will finish the commission even if I gave him the rest of the extra time. I sent him a message that I would proceed with contacting Paypal. A dispute has been open. As it is not yet a claim, Jors still has time to reach out to me and, hopefully, resolve the problem without Paypal's intervention.
I am not really sure if something happened to Jors that was out of his control and made him unable to complete my commission. However, nothing was ever communicated with me so I can only speculate. Also, he never posted proof that he donated the commission money that he received.
