I opened a business account and got 2000 euros transferred in it. Now its almost 1 week that i am not getting access to my account. Emails are replied after 2 2 days. They dont have a phone number or other mean of communication. When ever they feel they reply but dont give any solition to problem. I have a very bad experience. Will never trust online bank again
