Admissions never wrote me back?

I emailed Harvard admissions on a major update to my file. I sent it to the main admissions office and I sent another message to my regional admissions officer on the update. I also uploaded this information to my portal. However, does Harvard never confirm that it received your email? I’m just assuming because I’m sure they must be inundated with documents.

I faxed the info today (after an entire month) just to see what would happen. Am I worried for no reason since I sent the update 3 times?

*All the other Ivy League schools except Harvard & Penn confirmed my update

You have to remember that this is Harvard. Somewhere on their website, they state that they can’t confirm receipt of information.
