My Instagram Account is In Limbo

I created an Instagram account a few weeks ago. I use a password manager, Dashlane, which creates a password for you if you want it. I used that and I think I refreshed the page which caused it to create two passwords. So, I reset my password to make sure Dashlane had the correct one. However, ever since I reset the password, the account has not... existed? The username is taken, but any attempts to reset the password are met with "No user found". I know the account exists, technically, because the username is taken and I received an the one email about resetting my password. I called the Instagram help number and left a voicemail, though I may have been cut off, unfortunately. Any ideas?
