What is the ID-number of your MacBook?
e.g. MacBook7,1 supports High Sierra but MacBook5,2 doesn't.
Did you do the previous firmware updates?

Delete and re-download the installer should fix that, have you tried actually re-downloading or are you using the same installer you originally downloaded?
I already tried that as well, deleted it out of my apps folder then re downloaded it again, still the same issue even apple techs said it should upgrade.

Perhaps a PRAM and SMC reset?

Do you use a harddisk or SSD?

Did you verify if the harddisk is OK by booting in the recovery mode and checking the disk? If necessary, was it repaired?
To be honest, there isn't a big difference between Sierra and High Sierra.

Honestly I did all that came back with no errors and still does the same thing over and over
Yea apple was on and off the phone with me for days and then they just stopped helping
Perhaps the firmware of your macbook is corrupt.

It's difficult.

Ok my Mac is not on that list if you read down on the page it states if your macs identifier number isn’t listed then it’s a intel Mac and you don’t need this method
Create a bootable USB flashdrive installer, and try installing that way.
Get a 16gb flash drive and the free app "Boot Buddy".
It will copy the installer onto the flashdrive and make it bootable.
Then, boot from the flashdrive -- perhaps the installer has the ability to detect the firmware needed, and update as required.
Won't know unless you try it.

Did that as well... just seems like a a endless cycle does it over and over no matter what route I do

I suggest you reformat the drive from the bootable USB flash drive's Disk Utility before attempting to install macOS.
"Done that before as well"
When you did the erase, did you choose to re-initialize to HFS+ with journaling enabled, OR, did you use APFS?
That could make a difference.
If you continue to get nowhere, my best recommendation would be to "go back to low Sierra", and be happy...
