calm down, no big deal

You just need to talk to s few friends then calm down. They got the second camera, you will get your claim from FedEx.

You want to sue them? on what grounds? sue them for what? What is your damage?

You want to report to plice? report them for what?

It seems to me that your mental condition is not as stable as others in a similar situation. They buyers can of course threat to sue you as they did not get the shippment as promised. What is wrong with that?
