Upload & Sell: On
Sorry to hear this. The seller is a somewhat new member with very limited history here, this was her first sale, and her product photos aren't very clear. Her description certainly doesn't mention any damage to the filter rings. Hopefully you paid for the item using some payment method that carries buyer protection, such as PayPal. These intermediaries have established procedures for dispute resolution (if the seller doesn't resolve herself). For more info on PayPal's buyer protection, click here.
If you're covered by any buyer protection, pay close attention to what is required of you and any timelines that must be adhered to.
