Monese

Hello. I am having an issue with Monese Bank account. They've blocked my account and card last Friday (28/06/19) with a non reasonable explanation. I was just informed by email that the account is being closed. After several phone calls to their support line I couldn't get any more information. I have in that account +-£2680 which they said I have to provide them with another account details that I own so they will transfer my funds but I didn't get yet any confirmation of this. Also, After reading some reviews I found out that this issue is happening very often and I've read people stating that after 5 months they still didn't get their funds back. I need some help and guidance as what to do in this case, please. Thanks in advance.
