The support people told me that because of security policy it is impossible to send bitcoin out of WirexApp once you have sent them in.
The only way to get your money out is via the prepaid card which is limited without verification.
I sent them my documents at the end of December 2016, after three weeks of waiting I contacted the support. Few days later they replied that they sent a followup request to the authority that verifies the documents. They got back to me two weeks later on the day the documents passed the 3 months limit they require, stating the documents have passed the 3 months limit they require and therefore are rejected.
