What is the mean of not services by crex_24 . Are you cheating me? Here lots of exchange running in the market, once a time I am using binance and due to some mistake I have sent some xrp without Destination tag but after support I received the coin.
This to me sounds like a cross chain recovery issue. Depending on the exchange, and the size of your transaction, your funds might be lost.
