When you messaged them, did you send you wallet payment id found at brave://rewards-internals? Do not post your wallet id! Support staff need that information to troubleshoot your problem.
Post-May payout, support staff have requested you submit a request using different titles for Uphold, Gemini, and Unverified Wallet requests. You will have to submit your wallet payment id in that request as well as other information. Be as detailed as possible. I posted the Uphold request below in case you haven’t yet submitted one.
From previous topics, support staff have said that requests are put in a queue and support staff work on the requests in the order received. If you have already submitted a request, it may be a while until they get to your ticket. I think they notify you via email once a request has been fixed or if they need additional information.
