Lexus of Silver Spring

As previous review stated, my wheel was serious scratched especially inside the rim so I called just to let them know the bad job they did. I was told to just bring the car back and they'd repair the rim. I thought it was a good idea so I brought the car back. estimate was about 40-45 minutes. I waited patiently for 2 hours and came out to inspect with the service rep when it was done to find out that the scratches are technically the same. Someone cleaned it up a to make it look clean. Then I realized the wheel center cap with "L" logo was scratched. The service rep said he would replaced it and he did. Good courtesy service to the rep. BUT why all these scratches even happened in the first place? A Lexus dealer doesn't have the right tools to do these things to avoid damages to the wheels? Service rep did say that they had a $40K in the shop just to repair the rim. Then why the scratches couldn't be repaired? I was to the point after waiting over 2 hours where I said to myself "let just get the car back go home and forget about it AND never come back here again".
