It seems that the focuser is on the wrong position for the diagonal, you may need to cut another hole in the tube at 90 deg. to align them correctly. Seriously , is the diagonal way off centre in its holder, even allowing for collimation offset.

That's how it looks to me, as if it's been attached way off-centre. First time I stuck the laser collimator in the red dot was almost off the edge of the primary. I was able to get the dot where it should be after a LOT of adjustment but the secondary just looks wrong.
Doesn't matter who the retailer was / is, do they actually open the box and have a look down the tube and understand what they see, before they send it out or you pick it up.
Loosen the three hex bolts and then partially unscrew the centre screw, probably only need one rotation. From there you can rotate the secondary around, tighten that screw and then you'll have to re-collimate from there.
I had to do it on my dob ages ago after I was playing around with it, only took a few minutes to fix.

Ah, so it is possible. Problem is that the central screw was so tight it stripped when I tried to loosen it. I hate the fact that they use cheap soft screws in these things.
I already had a conversation with Saxon today before making a second attempt to fix it. Guess I'll be talking to them again tomorrow.

I bought it from Astro Pete's in Brisbane because his price was way better than elsewhere. Since I'm in Sydney it was shipped direct from the warehouse in Melbourne to reduce the shipping cost.
So nobody has had a look at it since it was assembled and boxed up in China.
Saxon called me today to check up on progress (quite impressed with their customer care). They're sending me a new central screw so I can replace mine before it gets stripped completely.
In a way I'm glad this happened as I now have a much better understanding of how the secondary mirror system works.
Before you go too much more with changing the bolt, put a little WD40 under the bolt head, and a little time for the oil to seep in. It will help loosen the threads and ease any damage that may have occurred. I'm talking a drop of the stuff, not a squirt from the can. If all you have is a can of the stuff, spray some onto a bit of plastic, or some other surface, and pick up the liquid from the material that's pooled. Any excess on the hub can be cleaned up when you remove the bolt & secondary mirror. You won't be putting on so much that it will coat everything! Just a drop. Dry lubricants won't seep down the threads where you need it.
