I’ve contacted facebook.com/revolutapp and Bryan helped me, without further notice.
I have sent all the paperwork to raise the account limit, indeed it was not necessary yet - and the 96 hours deadline was not accomplished. I cannot trust a company like this anymore, that is not absolutely British.
I’m available to face your security reasons anytime. Thank you in advance.
I would like to thank “Billy” from the account Support for understading my problem, he was really helpful. Now it is solved.
