Nope, they're asking for "supporting documents" (KYC, source of funds) which, from my understanding, the rightful owner doesn't want to send.
It is one thing to reject a deposit/withdrawal, another to confiscate.
BestChange should intervene. If they do not intervene and the funds are not returned, this will be a bad precedent that deserves a red label.
Every exchanger presented on our website has been thoroughly checked before listing, and the BestChange team constantly monitors exchangers' services quality. This minimizes risks when making financial transactions in exchangers listed on our website. Should an exchanger fail to properly fulfill its obligations, a number of measures would be taken against it which stimulate the exchanger to solve the issue as fast as possible.
