Not to be that guy but how long do I usually have to wait for a reroll to be approved?

I've been waiting for 5 days by now... from what other people say it takes pretty long now, up to week or more.
I'm btw more curious in another thing, what if they don't grant a re-roll (for example the person has already served the suspension), and 7 days will be passed already and the person marks "not received". I mean, I will send the key after support's answer but can he choose to ignore me and then I'm stuck with not-received or is he forced to activate the key even after 7 days?

27 days

¯\_(ツ)_/¯ it's a tossup. had one take 6days and just was dealt with 2days ago, then had another yesterday that was dealt with in less then 2hours that needed another reroll yesterday that was done in another 1hour.. (2 re-rolls in less then 4hours)
