All kinds of reviews about scams are hilarious. While the site of the sberbank has a license to operate and you can make a complaint in the scam. Apparently black PR is in force.
The license should be on the website of the Central Bank (not Sberbank), but there is only information about opening a license in 2016 to work with Russian exchanges and it was revoked by UT itself in 2019. Moreover, the license is not of the type required to conduct independent activities with exchanges. According to it, they can only take the dough and transfer it to the broker for use =)
They are licensed as an LLC in Russia. And when you deposit the balance you transfer the money to the account of an offshore company from the British Virgin Islands (BVI ltd).
