he managed to stop the rattling but he could not stop the nasty vibrating noise
First time he filled down the frets and adjusted the neck
second time he done the same ( as far as i know )
That does sound strange.

It could be... well, to make qualified assumption it would easier with more details about the bass and setup, but it doesn’t seem like you’re in the troubleshooting mode with this bass anymore, so.
But of course, it’s annoying needing to do any troubleshooting on a new bass, especially when it has been setup by someone that should be able to do it properly.
Anyway. When they couldn’t fix it they second time, I think maybe they should
not have just sent you home with it again, but exchanged it or given you the money back.

Well, one does hear and read a lot of nonsense. One need to have a basic understanding of what to do and why, but it’s not magic. If we leave string height at the nut out of it, there are basically four adjustments; (1) adjusting string tension for tuning; (2) moving saddles back and forth for intonation; (3) raising and lowering the bridge to adjust string height; and (4) relaxing and tightening the truss rods to adjust bowing of the neck.
Patiently working on the setup step by step, one shouldn’t (usually) end up doing anything irreversible. Lots of guys here on the forum to walk you through the setup – next time
