Repair work done after front end damage-condenser replaced- now compressor is bad-shop says it’s my problem

Condenser damage, caused by front end collision, can damage a compressor too even though the compressor won't get physically hit/smashed in the collision. If the compressor is clutchless, like on most recent VW vehicles, the compressor is always driven by the engine, and no refrigerant means no lubrication flow at all (in automotive ac compressors, oil is carried around the system by the refrigerant since there's no dedicated oil sump and pump built in the compressor unlike with AC compressors meant for buses such as the Seltec/Valeo TM31) and this means compressor seizure. I prefer clutch equipped compressors for that very reason. Check if the compressor on your vehicle is clutchless and if so check if the torque protection device on the compressor's pulley engaged and separated the seized compressor shaft from the pulley. The problem could be showing proof that the AC compressor was healthy right before the collision.

Even better, post a picture of the compressor pulley's front here so i can check myself.
