So far I have not tried sending a coin to an incorrect wallet address because I always check a couple of times before confirming the transaction. I make it a point that I have entered the correct one because I don’t want to go through like those other people who are having issues with the customer service.
Better doing this before dealing with exchange, the service personnel will have to look at it for such a long time, we should need to be very careful
as it's not their problem but it was our mistake, I think we should wait if ever things like this happen to us, patience and more of it while waiting for
any comply from the exchange itself.
The OP was the one who made the mistake anyway and I think that it is not the exchanges fault if it will take awhile. There are reminders to check the address we use for sending and make sure that it is the wrong one. Their customer service is bad because I have also encountered a problem here when my withdrawal took weeks before processed and I was really worried that it will not be able to get it in the end. I did not receive any reply from the customer service so it was a good thing that the OP receive one.
The lesson here is to check everything before confirming because we all know how hard it is to tract transactions, what more if it is to recover what is wrongly sent.
I use HitBTC for buying Tokens since it is the only market for Ethereum tokens, second to Etherdelta. I like its design and simplicity of HitBTC. However, the fees when depositing and withdraw are pretty ridiculous, they charge roughly $16 when withdrawing tokens.
I also used HITBTC because the site is more faster to load than Etherdelta. It just make me nervous if I am processing good amounts because there are security issues and trust issues about HitBTC.
