They don't implode any more.Even though it is only a month old I would get great satisfaction from dropping it from a great height onto a solid surface!!
A month is nothing. Follow Sharkey's advice and take it back. Personally, based on what you've said I'd class it as "not fit for the purpose for which it was intended".
The fact you haven't kept the packing on such a large item shouldn't be a problem.
