How do I resolve vibration/haptics problems on iPhone 14?

So, a few weeks ago my phones haptics were acting weird. Every time my phone would vibrate, it would be louder than usual and make a weird quack like noise. I took it into the Apple Store near me and I was told that my phone had some sort of loose part. Yesterday, I got it repaired, though, now I have no vibration whatsoever. I went into settings and I have tried absolutely everything, alone with restarting my phone. I repaired my phone with its free warranty and I’ve had it only about six months. I want to avoid spending any money, and i feel like the problem should’ve been resolved the moment I picked it up from the Apple Store.
