How long does Roblox support usually take to answer a ticket?

make sure the email on your account is verified and one you actually check, the reply goes there, not to your roblox messages. and look in spam. half the time the 'no answer' got answered days ago.

There isn't a fixed time. Mine came back in a couple of days, a friend waited over a week. Don't send the same ticket again though, it doesn't make it faster and can make it slower.
