Accidentally locked my laptop from my Microsoft Account. How to unlock the device

I don't seem to have that simple an option. When I get to the log in screen I am able to log on. Yet I have an email saying that my Device has been locked. This was done in error, how do I reverse and unlock?

Tried entering the password but its looking for the PIN and will not recognise the PIN

Listen up! There is a way to unlock your computer without doing a complete swipe. It took me 2 hours after I found a person in microsoft to assist me. Do not attempt this without their assistance. you have to open in safe mode and type in specific code. I do not have it readily available. BUT it CAN be done.

It doesnt work my laptop only gives option of a pin. But anything I enter sez needs an admin to log in yet thee is no way to get to a log in screen

So where is the solution to this massive problem. Under devices in my account it doesnt give an option to unlock just to lock. The laptop want a pin then an admin access yet no way for an admin to log in WTH are we supposed to do.
