The A/C compressor and for her to not run the A/C?

My kid is out in California (I'm in Florida ), couple months ago, the engine started to make a noise. Took it in to a shop, they said it was the A/C compressor and for her to not run the A/C so nothing internal would get contaminated. So she hasn't.

Now to today, SUV wont start. Towed to same shop as above. They told her " the A/C compressors front bearing/pulley locked up causing the no start, but nothing internal was damaged so no worry for contaminates". They recommend a new compressor and belt.

The Rogue's clutch on the compressor is replaceable, so doesn't it make sense the noise that was heard originally was the bearing in the clutch and now it finally locked up? I don't know for sure if the Rogues compressor has the bearing in it or if in fact its at the front of the compressor (if its at the front of the compressor, okay I can see a new compressor), does anyone know? I know its really hard to say what the original noise was, I just don't want her being yanked for $900.00 when all it is, is a clutch, but since she's a young girl, eh she doesn't know any better, know what I'm saying. Thanks
