To be honest, I got it like this. I was able to get the original owner to remove it from his account but the mac remains the same and there is no change, still asks me for the login information and the owner does not remember the mac password and he does not want to give me his account so I can enter here I only managed to remove it from his account

That would indicate the original owner did not, in fact, remove it from their account.

Return it and get your money back. There is no way to bypass the activation lock.

You're not going to be able to fix it. Only the owner of the account used to lock it can remove the activation lock.

if i try to use the internet recovery what i get is the activation lock screen and i have no other option. I have to erase disks and reinstall OS. and i cant make the mac boot into usb

Sounds like you did not "fix" the activation lock issue as you previously stated. Was this computer previously owned/managed by a company/organization?

This tells you how to create a working bootable flash drive and install your OS: Create a bootable installer for macOS - Apple Support

Is there some reason you aren't using Internet recovery?
