Thank you! :) I guess you didn't place an order by using the telephone? Note that the phone also has letters on the keys, and there is a strange message on the shower door...
It took me a while to figure out the ! but I got there in the end!
Yay! I put the hint for ! in the Maintenance phone message, dunno if it was too vague... Did you finish the game?
Yes the rest of the game was much easier for me.
