I have requested two withdrawals of Ethereum yesterday and show the same error "Sorry, We are unable to locate the Transaction Hash", following are the Txid's:
0x0f21bc2f822e4755e60ec988f6f2e3e6aac1c50194ee6d58f5ea52339deb5542

0xed13b8ca82c7c9cc51abf635dc04e8603dbf0900b35abd996c446722f105ca5a

I don't know how to deal with this exchange, has high potential of trade but these issues halt its progress!
