Used 2020 model 3 Performance: Metal shavings at hub

[Booboo22!]

So I've been dealing with vibration since I took delivery of my used 2020 Tesla Model 3 Performance. Apparently my service center isn't shall we say the brightest crayons in the box. I told them months ago I thought it was the left front wheel hub they replaced all three other wheel hubs except for the one I thought was bad. Until I went back to pick it up drove for a few moments and noticed it was not better. After they did replace the front left the vibration got a little bit better but was never fully gone. They even changed the front CV half shafts at one point. I was driving home from the service center after that replacement and I felt something different as I was 5 minutes from my house. After I did get home and checked there was CV Grease everywhere. The brand new half shaft boot was sliced in half and again the car had to go back to the service center. So when this vibration continued and I still could hear it and feel it in the front left even though now it's in the rear cuz I can feel it in the seat as well because they haven't fixed the issue. It has only gotten worse effecting other areas. I decided to take the front left wheel off and see if i could find something. Only to discover that there are metal shavings and a little bit of oil where the Hub and wheel meet. Not to mention I'm almost certain they were not torqued down to spec. The service center last time I took it said it was completely fine they heard no noise and felt no vibration. Kinda made me feel a little crazy like i was imagining it.. So before I go calling to make an appointment I wanted to get others thoughts on this. Also the caliper mounting bolts have metal pieces coming from them. This car has been a nightmare since day 1. Where the SC has had tue car longer than me at this point.
