I bought an LED Retrofit kit for my Biocube. It came in the mail today, but one of the parts was damaged (the fan inside the power supply had a blade broken off). I already contacted the guy who sold it to me, he's filing a claim with USPS since it was insured and they quality control everything as it's shipped. I have pictures of the broken piece, which I sent to him. What else should I do? I bought it with a credit card, so I can call them up and get the charge refunded but I'd rather not do that until after I see if the seller can work things out (I've been on the receiving end of Credit Card douchbaggery and it sucks).
