Wirex is a well-known scam before but there are people telling that it is not a scam I think 40% to 60% telling that it is not a scam so we don't know if the Wirex service is trusted or scam.
However, since their support still active maybe we can still trust their service but not 100% and I heard that there are many Wirex users abuse their service that may cause issues like blocking or locking your account if they detect any suspicious from your account anytime they can lock or block your account.

This is just what I heard from some marketing forum who abuse the Wirex app for making multiple accounts.
