Issues with Stillen lightweight crank pulley

[nomodsjk]

I am wondering if anyone has had issues with after market lightweight crank pulleys damaging serpentine belts, barrings or altinators? If anyone has read my thread about my csf radiator install nightmare this thread is related. Today, after a long ordeal with the dealership botching the installl, my ac compressor went out. This was the first time since picking up the car on Tuesday that I've tried to turn on the AC and immediately the compressor seized. I was told this was a coincidence and had nothing to do with their work. They told me it was related to a faulty after market part and pprobably had something to do with my crank pulley. The compressor went haywire as soon as I turned on the AC. I refuse to believe it's a coincidence. They told me they will not work on my car anymore and to take it elsewhere but they will reimburse me after the fact. It's been almost 3 weeks and cost me 1014$ for the install. I'm really mad and I feel rightfully so. Can someone please tell me if my Stillen supercharger kit could cause this? Please
