A big camera battery ****.

This is a blatant con,they show camera batteries,and once you have paid,and received all the nonsense of what you have purchased,etc,then they come with a story, that they are unable to supply the batteries, due to a ban on the import of them. They now ask if I want to have a credit,which I have told them I do not,and want a total refund.but they don't answer.
