I will go ahead and shoot them an email based on the posts here, and we can see what happens.
I'll keep you posted when/if I get the reply.
In my opinion, if you plan to actually use the product in the dented cans
the objective would then be to inform them of a packing or shipping probem
so that they have opportunity to correct it. I would then say upfront, I'm
NOT looking for a refund or replacement, but I would like to inform you that
X number of cans arrived dented which makes me reluctant to reorder
in the future.
This would give your complaint credibility and they should take the problem
seriously instead of suspecting that it's another customer looking for some
free product. They'd also have to consider the loss of future business
and might even offer you a coupon for use on a future order.
