I have been using purse.io for a few months now. Made about 4 transactions and I have never had any problems. Purse.io is as legit as it gets.
In case you tried buying inexpensive prepaid cards by trading bitcoins or amazon gift cards then it might happen.
Please, I've heard rumours of it being run by 2-3 people instead of a group. I don't really trust a .io, they have no trust ratings. Also, please show proofs your transactions and the amount risked. 200$ is not a joke, it needs to be considered while joining a website that gives no prior reason or warning to the users.
