I don't know who the manufacturer is, its not important, but would be nice to know.
Regarding your issues, I would return it. You will never be happy with it, even if it performs as well as you hope.
Warranty does not start at date of manufacture. Warranty starts when sold, for the first time. Dealers who use a piece of gear for demo purpose effectively start the warranty, unless they have a special relationship with the mfr/distributor. I am sure some storefronts use gear as demo, and then sell it with full warranty.
As far as the bait and switch on the faceplate.. definitely an operation I would avoid. I wonder about how good their warranty is?
Its a shame, buying new gear should give you a good feeling, not this.
