They are scammers they use their own account when purchasing tickets to ensure that if you do apply for a refund from the actual airline that they will keep your money until you complain and I mean alot then they will take fee after fee, let alone we are entitled to a full refund during a Pandemic in truth they are going to get sued and their name has been tarnished already I will be contacting the airlines about their fraud
