i forgat my password and they told me to call itunes

Password or passcode?

If you forgot your passcode (a four or six digit number used to lock the device) it is stored only on the device and so cannot be retrieved. You will have to erase the device - please see the page linked to at the top of this page.

If you forgot your password go to https://iforgot.apple.com

Keeping in mind that if you don't have a backup all data will be lost on that device (except those that you eventually synced to iCloud), pay attention to the specific gestures that you need to perform while connecting your iPhone to a computer (Windows 10 PC running the latest iTunes version) or Mac (which can have iTunes or Finder, depending on the macOS installed on it), and follow these instructions to re-gain access to your device:--> If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support
