I did contact them via email and further tried to contact them via phone multiple times with no luck. I was pissed and wanted a answer, I got a very elaborate answer from them and acknowledged I was thankful. Sorry for not wanting to spend $16 shipping on a $45 rail, you are more than welcome to spend your money however you choose.
The problem I see though Zback is that the issue you have isn't really about the $16 separate postage fee, is it.
What you have done or tried to do, is to seek to destroy or tarnish the reputation of a business because you couldn't get all that you wanted instead of what you paid for. The fact that the extra cost to you was, as you've stated $16, it can't have been the cost in pure money terms.
In your mind, that $1300 you paid for the press, buys a whole lot more, doesn't it. Not because it's $1300 but, because it's your $1300 that you have blessed Area 419 with, in exchange for the press, isn't it?
I'll bet you have this trouble all the time with everything you buy. Rude customer service, fit & finish never up to scratch, wait times always too long & on & on, the list never ends.
I think the problem is really your problem. Mommy told you your whole life how wonderful you are, always let you interrupt the adults conversations, never forced you to take responsibility for your actions, never made you persevere, never taught you patience, never spoke about the position or plight of others around you.
Because of the likely possibility that you have no concept of what you have tried to do, I'll state it in plain terms:
You tried to destroy a company over a $16 postage fee.
You tried to destroy a company over a $16 postage fee.
You tried to destroy a company over a $16 postage fee.
You tried to destroy a company over a $16 postage fee.
This kind of vindictive behaviour reveals an acute lack of empathy which, usually culminates with some significant level of sociopathic malevolence.
You really do need to consider very carefully, your perception of reality.
