wirexapp is a legit company so far,they're reputable service as far as i know.
but their costumer service is nearly zero,because they don't really care about their costumer.
unless you deposit a huge sum of money to your account.
have you contact their support ?
because i heard someone have a problem with them and after a few tickets and complain they're answering your question.
they have a high fee according to their statement but it's not fixed yet,it can be vary if i am not wrong.
or try to contact him directly in here :
