Glad you enjoy what you have seen of Alpha so far.
Now,
Assuming is what got me into this mess in the first place, and I will be the first to admit the mistake was originally mine because I was excited about the game.
I've made many mistake using this method.
So, basically I was led from the Kickstarter page through a link to the "new" online store on the premise that I believed the rewards to be the same for either.
Agreed, the Kickstarter page does not indicate that supporting the game would be any different going to the website; however, as the KS project had ended quite a few months back it is not unusual for local procedures (in this case the store) to change.
The packages for both the Alpha level in the Kickstarter and the Alpha level on the new store were titled the same and cost the same and so I thought they were the same thing and purchased one.
However, (at least under the current page) it is clearly indicated as of the second paragraph of the Alpha description as to what you get. Other than access, (Alpha / Beta), the game and expansions there is no mention at all of Kickstarter rewards, other than the old backer app FAQ link for the previous KS backers. Perhaps Frontier should specifically place a warning that there is no Kickstarter rewards available on the site? I think this would be redundant IMHO.
I loaded up the game and played through twice (once to figure it out, and once to put a video on youtube to show the game off) and then wandered to the forums, after reading through the forums I realized that apparently I had missed the timeframe when the rewards were the same by less than a week.
Here is where that previous "assume" word came in and bit you here...
I then proceeded to create a post warning other people about not making the same mistake (which got locked)
I did look at the post, and it got locked as it turned nasty and ran it's course, not because the Mod singled your posts.
and then I made another post to possibly change the alpha and beta package to something slightly more reasonable (which also go locked because people treated it as the same as the first post even when I requested several times that they not do that) so that I would not need to seek reimbursement because I thought the game would be worth the money if they just provided some kind of recognition to "new" store backers.
You forced the hands of the mod on the second post.
After that was locked I PM'ed support asking for a full refund (I was admittedly already upset at previous treatment) at first and then changed it to a partial refund after their company policies were explained to me.
Since then I have been told that they are unwilling to work with me at all despite requesting the refund extremely quickly and explaining that the purchases was made under false assumptions about package contents.
However, and unfortunately, they are your false assumptions as Frontier is clear on the store page as to what is included.
I have suggested several different ways to resolve the issue that I would be happy with and Frontier has so far not been willing to compromise at all, basically just feeding me their company policies over and over again to each one.
Now you should be caught up, the whole process has taken over a month because there was a claim filed with paypal over the issue, but paypal apparently does not handle claims for virtual or digital goods at all.
Sometimes the only solutions from those 6 letters (Assume) is to learn from them and grin and bear it.
The KS process and rewards for just about every projects thatI have seen and supported always include extra for the backers brave enough (or foolish as some projects don't make it) willingly promote a product or company. If nothing changed after the period, then what would be the incentive in many cases to support? Once a project is funded, the level of risk for those that come later is much reduced and the same incentives don't need to apply. Does it makes KS special? Well, it does to some extent and I dare say that's life.
No hard feeling, and I hope you can eventually make peace with FD.
- Oh, I can almost guarantee that thsi thread will end up being locked too.

.... I see that I've been ninjaed by the mods and proven wrong... good!
