My bank freeze my money because I received transaction from another country...they are playing police

I am really pissed off...My bank decided that the money from my client in another country is not trustworthy. So they urge me that I have to justify this income. They gave me 2 hours to solve it, if not they would send it back.I need that money urgently and really badly. So I send them the invoices and told them that now they have all the documentation.....BUT NOW!!!They are saying that they need 48-72 hours to verify the invoices and they have to judge if that documentation is not correct in their eyes they can decide if I can get the money or not. They have full control over my private income right now. (A PRIVATE ENTITY!!!!) That means I am screwed for that time to get my money.I told them that that job should be done by the tax authorities. I have to respond to them, not to my bank. They are telling me that because of a new law they are allowed to do so and that have all the time they want to check me out. Everything is legit. But even so I have to hope that they do not send the money back.This starting to be a control state. The banks are doing the police work. They are doing the tax authorities work. They can stop any incoming money and not accept that because they can hide behind a law that gives them pretty much the right to cut you off the financial playground. This is scary.​I am from Spain btw.​Short bankers, Long Bitcoin via /r/Bitcoin http://bit.ly/36y6c9X
