Account frozen but verification not possible

My account has been frozen, I need to verify again (although I am a customer since years) but the app does not really work - when I try to answer the questions of the verification process (= source of money) always an error message occurs! It is also not clear for me, if Wirex just needs a verification of my address or of the source of my money or both… I asked the support and reported also the error messages, but I always get very contradictory answers!

I am willing to clear all questions and to provide all relevant documents. But that seems not to be the interest of Wirex. My patience is wearing thin, if I still have no clear response till the end of this week and if you keep on refusing me the access to my account, I will mandate my lawyer to solve this problem!
