Quite, this is a totally winable case. The packaging doesn't matter at all and an item has to be fit for purpose, not working after an hour is totally unfit for purpose. See my previous post.Stanleys right.
Twas a POS from the word go apparently? An hours use? Come on!
Stop playing nice, and find a way to ship it back. (A minor task for an elzedder).
Did you pay on a credit card?
And re the credit card, you have to act quickish with this, you only have 100 days I think if you want to go that way. But even without it, they have no chance.
