At 12:44 PM on March 24, 2026, I deposited 499.975 USDT in cryptocurrency (Figure 1), but it hasn't arrived yet. I've contacted customer service, and they keep saying they've expedited it and will reply within one business day, but there's still no response. I've also filed an appeal, but still no reply. The block status shows "Success," and the on-chain confirmation indicates normal completion, but the funds haven't arrived.
