How to sign in to Apple ID after attempting with correct log in info requested but receiving incorrect log in notice

I literally just made a new Apple ID and immediately following that process and attempting to sign in so I can download an app for free, I get a notice of incorrect login information which causes me to have to go back and re-check that I put in the correct information correctly, and try again over and over and over until I'm blue in the face! Then I have to spend countless hours searching for answers to why this is happening and make new accounts and passwords that don't work and then make usernames that they won't accept and all this other malarkey. So now here I am on day three of having a new phone and even though I've owned an iPhone since the beginning of the iPhone time, still the same troubles persist to exist with every Apple ID I have ever made.

at this point I deserve a free phone for putting up with it and all the other issues that I have dealt with over the years and sticking with Apple all throughout the entire time.

What is the solution for this issue?

what is the solution for making a brand new Apple ID and password, then immediately not working the way it's supposed to please someone tell me what the solution is so I can get on with my life?

thank you in advance.
