Sending an unsupported coin, using the wrong network, or sending a different amount than the order requires can cause a delayed or lost deposit. That is why it is so important to confirm the coin and network shown in the app before you send.
If it has already happened, send your actual transfer details and TxID to support, with one entry per transfer if you sent several. Whether a wrong transfer can be handled depends on the actual situation, so please do not send extra funds on your own.
