Query: Used or refilled cartridges

I have been purchasing from Amazon for over 10 years now, and have never posted a review. But I feel that I was ripped off this time. First, these cartridges are not new. They are refills. Second, they are bad refills. I ordered two cartridges, one of which has no blue color. I should have ordered directly from HP. Nothing I can do now because I am overseas with a cartridge that doesn't work.
