I tried searching and found that they have an account here[1] (no longer active) and it has been since 2015 without complaints of scam or customer problem.
For this, it's best to seek out help from a spanish speaker as it does look like they appeal to them more.
From what I can see, most of the threads mentioning them (in bitcointalk) are also in spanish local board and so, you may try asking there (unless english posts are not allowed in the board)
Some fairly recent:
