Comdata pay card Blocked my card and took declined fees. Internet

My card was blocked without me getting any notice. So I'm trying to use my card to pay bills etc. and it kept being declined. So they take all theses declined fees out of my account still without me knowing they put a block on my card for no reason. So I call and they tell me its a block. I explain to them I know nothing of this block and how they have took my funds out of my account and she says the only thing we can do is send out a new card. Im like what about my money you guys have taken out she quickly avoids question and hangs up. That was my bill money. I just want my money back.
