The broker blocked my withdrawal with lame excuses

My request to withdraw 1,500 euros submitted in May kept pending on without being solved. I've followed up my request by contacting them several times but the "support" system which hadn't been supportive at all keep saying they're processing the request without getting my problem fixed. Then there's this notice that they're having some kind of “system maintenance ” that seemed to go on forever...I guess that my money is as good as gone
