Hi. When this situation happened? If your friend already gave transaction ID and address - it should be fine. Maybe some technical delay. Similar issue was discussed on Reddit - https://www.reddit.com/r/Stellar/comments/7fei7r/missing_xlm_deposit_in_bittrex_due_to_no_tagmemo/
Hey! It has been a week! I read similar topics on reddit, but they didn't help. I m sure Binance is helpful but i don't trust Turkish Exchange(he wrote them too and they simply replied 'forget your money'). Is there anything related with them on this issue ? Maybe thats why he is so desperate now. I m the one who pull him into crypto business by the way =) Thats why i feel a bit responsible for that. I want him take his money back very much...
