How long does it take to get a email back from customer support?

I don't recall clicking on any links or logging in to any suspicious websites..

Well none of the links in the game are actually clickable, you'd have to specifically copy and paste to access them, but they're also intentionally disguised as official Square Enix sites to make people give them their login details. That's unfortunately why they work so well and people get their accounts compromised.

If I say used say 10 or 20 of those in Gridania.. used 1 every 5 seconds or so.. would that be an offense worthy of being suspended over?

Well I'm not Square Enix, but I don't see how. Using a firework doesn't even put it in the public chat log so it would be visual only "spam" and I've personally never heard of anyone banned for setting off lots of fireworks, especially not during Moonfire Faire.

Sorry, but either way you're just going to need to wait for SE to come back to you, but I'm sure whatever it is you can get it sorted out.
