How long does it take for SG to answer your tickets?

Recently, they've really sped up. When I make a ticket (and I can say I've made a couple), they usually get back to me within the hour.

This kind of request can take some time, since only the admin of the site can change your region.
Spamming tickets doesn't help, you should close one of these 2.

about a week after judgement day, is the general rule of thumb

Its either very quickly or a very long time. There doesn't seem to be much middle ground. My ticket is over 3 months, and I've heard of ones taking a year.

100

If it's about reroll etc I think it's pretty fast.

For Steamtrades support, it's non existent. It's beyond lazy. Like, SG is their golden boy and ST is their adopted son.

I sent a ticket about a giveaway question and they answered within the hour, i sent a ticket about adding a game to the giveaway list that i want to give away and its been a week and still no word.

I've submitted four tickets, one was answered the same day, another within the week, the last two I closed myself after the giveaway I reported was deleted, and the last I closed after the author edited his post and removed his reference link

Only admin can change region and from I've seen, he usually answers all of the tickets in one go every month or so.

Three months waiting for my request to be unbanned from the chat to be addressed.

How to send a ticket??

The one time I had to send one I got less than 5 minutes response.

It depends

When you look at the number of days your ticket is open:
