Did the same thing only I sent BTC to my BCC address. I actually thought I was sending BCC (long story).

I get that it is my fault. Lesson learned and all that but a new exchange should be trying to make a name for themselves by going out of their way for customers. The funds are recoverable and I get that it is hassle for them and am more than willing to pay for expenses but not even entertained. It a huge problem on KuCoin. A simple google shows up countless threads with people who have done similar. Rather than dealing with individual cases they could credit accounts and then do a sweep of all the effect account in one go later to recover all the funds.  

Many institutions could tell customers tough shit all the time but they don't because they understand how it reflects on them in the long run. KuCoin don't care and I think that should tell you all you need to know about them as an exchange.
