I signed up for Revolut because of their great sounding offer for currency transfers and paid them for their premium service. All was well until they asked for my “source of funds” details. I provided this information but then got stuck in an endless loop of unreasonable requests for further information about myself and my husband. The customer service agents never answered my questions properly and I was worried my savings would get frozen. Shocked that I paid so much money to be treated this badly. My advice: definitely avoid their service except for dealing with trivial amounts of money, because of this catch, and certainly don’t pay for it.
