I can't seem to cancel IDnotify and they do not answer their phone. Please help.

other than keep calling, your only other recourse might be to contact the BBB  or Federal trade commission.

IDnotify just answered promptly when I phoned the contact number on the page  below.  It says answered "24 hours."  And the agent confirmed to me they are open 24 hours.   The initial automated message will tell you if there is a short wait.

There is also a phone number shown in the FAQ below, which is different from the above, but it has the same automated greeting.   It also is available 24 hours/day.
