This sounds like Costco returns......my son works in that department and the stories he tells, you can make a sitcom out of it.....You guys have absolutely no idea how bad some people can get. Nothing tops Amazon customers.
We once received a "Returned" "BioCube 16LED" that was actually an old coraline covered Oceanic BioCube 14. It had to have been close to 10 years old. Amazon said that the customer sent the item back and the weight and dimensions looked correct so they got a refund.
It is as if people think it is okay to steal from Amazon because it is a big company but many Amazon sellers are not a big operation. They are small family businesses just trying to pay the bills.
