They will never replied you, because they know it as a fact the case does not work, and they do not have a correct case to replace you with....nobody has the right case as of this moment.
My recommendation is to file a paypal dispute ASAP. If that doesn't work(sometime Paypal are just bias) file a dispute with your credit card company, and get your money back. Negative feedback it so other who is buying the same case will know(doesn't work too well; but better then nothing)
