Transactions often drop out of some nodes but are then rebroadcast by other nodes so they reappear.
The fee is actually 0.00040718 BTC/kVB which is unlikely to get confirmed anytime soon. Firstly don't worry about it being an attempt to scam you. That would be a very silly way to try and scam someone as they have no control over whether the transaction gets confirmed or not. Secondly, there isn't anything anyone here can do for you. Only cex.io can resend the transaction with a higher fee.
Thanks for time and answer. I m trying to contact with them. But it is useless.
The only way left is request a help from miners so.
I hope i can find someone who can help...
Have a nice day.
