Can I report for being vote dismised?

[Gallus]

I don't even know what the hell happened, this is the first time I see this, I was on a wanderer's palace HM run for my BRD relic, and suddenly, after the second boss, I was dismissed, my DPS was really good, I didn't say a thing, I didn't pull before the tank did, I splitted dots to make run faster but always trying not to rip aggro from the tank.
Suddenly, out of nowhere, I'm dismissed. I even checked their names on the lodestone...and bam...healer and tank from the same server and FC.
I'm so pissed atm I could spit fire through mouth. I'd love to punch them on their faces.
Isn't this reportable? I mean dismissing for absolutely NOTHING? (they never communicated, if I was doing something wrong -???-, they could've said at least what).
