apparently my problem has been resolved. Although I want to list the details of my case as it my help others, and also express my questions about the process.
As already said I had someone transfer me money to the revolut account. The support person that helped me, asked that I submit a screenshot of the transaction from the sender’s bank. Despite me asking how is this relevant I got no answer. And the fact that my account was not blocked when I received the money, but hours later when I begun spending it, enforces the fact that it has nothing to do with it.
If you think of it, it’s kind of absurd to get your account blocked when someone sends you money. That’s what a bank account is for, and without it, it is mostly useless. I did also ask if this will happen again in the future and was assured it will not. Lets see.
TL;DR: If your account is blocked and you have received a transfer (I can assume its for new accounts mostly) - secure a screenshot from the person that transferred you the money and await for the support personnel to reply to you. It might come in handy!
