Yep they are shitty. You have to be careful when buying as they automatically set the price per coin to almost double of what the current price is. For example, I was going to buy some WTC which was at .0028 Eth. When I chose the amount of WTC to buy I saw they had automatically filled in the price per coin section at .0044 Eth! I was like wtf? And I had it in limit order mode so imagine market order! Moral of the story is be weary of coss.io. Definitely not an exchange for newbies. Their withdraw fees are thievery also. Won't be using Coss.
