That's just the kind of world we live in, unless the submission has what the publisher is looking for depending on the genre, beginning chapter and character descriptions you can't really expect nothing except a ray of disappointment, knowing you waited for 3 weeks or 2 months that felt like an eternity just for no reply, it's honestly a kick in the ass, but you also got to remember that they have tons and I mean tons of submissions to go through and reply if it suits what they're looking for, it sucks but that's just how things are unfortunately
