How long to wait for Support to reply?

My friends being trying to change his phone number and is still waiting on a reply from in-app support?

What’s the waiting times like?

Your friend can change their phone number in app or, if they don’t have access, try sending them a tweet.

Neither of us can find a way to do it an app.

Sure we can tweet them, but it’s their direct support? Seems madness.
