I have completed the quest Innocence Lost and have waited for days, yet I have not received the letter from the Dark Brotherhood. Nor does sleeping for 24-day intervals work.
Is my game glitched, and if so is there a way to fix it, such as a console command to trigger the quest?

Having completed the "Innocence Lost" quest, I immediately fast traveled to my house in Whiterun and slept for 1 hour, the kidnapping took place straight away, there was no delay.
It has been noted on the wiki that:
Just keep wandering around a different town and waiting until the courier arrives, it's been suggested this can take many days in game.
