I accidentally made two transactions to the same address when I made a swap at Quickex. I contacted their support agent via chat and described the situation. After I provide requested proof I was told to wait. Eventually, the second transaction that I send by mistake was returned to me! Thank you for good support and honest service!

I exchanged BTC to TRX, and the speed was satisfactory. I initially checked with support regarding the large amount and was assured there would be no issues, and that my transaction would be monitored. Everything went smoothly indeed. I plan to keep using this platform.
