Hangging

Last day I trade.. I want close all at mt5 DM but hanging around 1 hour I have prove I have screen video I have screenshot all anything.. Then I text the customer servis DM he side say thare it will check the system but not take responsibility.. Now my I lose my money then no refund?? Not my mistake all about your mistake fucking system.. Then how??? Always hanging mt5 DM... Hope it doesn't happen to anyone else... Very disappointed for this broker.. Last I use this DM..
