SC-450Plus GT Vintage Series : A little disappointed

Out of the box the guitar looks gorgeous no flaws in the finish it weighs 3.7kg sounds great the volume and tone knobs work the way they should very smooth and the toggle switch works well feels good too. Now comes the disappointment the guitar out of the box came with high action the frets needed polishing. Polished the frets lowered the action BUT the neck was bowed watched YouTube how to straighten the neck did that all good so far then I lowered the action I get the action to where I like it and start to check for fret buzz I start at the high E string and work my way down the neck note for note all good up until I get to the low E string start to work my way down all is good until I get the 9th fret bang fret buzz but the funny thing is that it’s only the 9th fret on the low E everything else is good so I have to rise the action on the low e side to the stage where I it’s not comfortable for me to play it’s playable don’t get me wrong but I would rather the action lower. I’ll take it to luthier friend to see it if the guitar can be fixed with no extra cost I’ll keep it for sure if not it’s going back
