So you're saying that they cant be trusted just because of that issue? They've been here on this market for a while and its just not right that they are just try to get money at all cost.
If you do have pending btc transaction and you do decide to make up some ETH withdrawal and did fail then it doesn't mean that you had been scammed.
It do really give out some questions in mind on why the heck it didn't able to go through.Its not something new because there are features where you cant make
any transactions when you do have a pending one.
Making out complaints then better go approach them and tell your concerns.
