The Radiance patchnotes state, 2 challenges per day for the entire duration, i.e.:
27 days of the Radiance event * (1300 + 350) = 44550, plus the free 1st level =
45 Radiance levels by the last day, with 550 XP remaining.
The patchnotes guaranteed 45 levels implicitly, and if someone bought a BP assuming they’d be guaranteed at least 2 challenges per day, that statement is a part of a binding legal contract. You can say anything, and if you go back on your word, you’ll only damage your reputation, but if what you say or write makes someone give you money, it’s something else entirely.
If I tell a neighbor, “You can park in my driveway for free,” but then I place a fence or a chain preventing them from parking there, they can’t complain, cause it was free anyway. But if I tell them “And if you pay me $30 a week, I’ll also wash your car every day,” and then I stop washing their car, they have reason to feel scammed.
I do believe that anyone who bought a BP and feels scammed has a valid reason for a refund. Though Gaijing would probably suspend their account. The ToS probably forbid me from recommending to do a refund, so I’m not recommending anyone do a refund. 
But, should one feel inclined to try, it should be as simple as linking the Radiance patchnotes with the refund request through an appropriate Paypal form. And make a screenshot just in case, should Gaijing do a mickey and delete (something in) the Radiance patchnotes (again, I’m not recommending doing a refund, a screenshot would be just in case you want to preserve that part of Crossout’s history ). It stands to reason that, should one want to do a refund, they may first try explaining it in a support ticket to Gaijing that:
- They feel scammed, seeing as the Radiance patchnotes implicitly guaranteed up to 45 levels on the last day, and it’s now obvious they won’t be able to make level 45 on the last day, because it’s clearly stated there won’t be any more challenges, which means 37 is the max.
- Seeing as they wish to cancel the Battle Pass purchase, they don’t need the stuff they received with the BP anymore, and could the support please take all of it back, because they’ll be doing a refund, and they don’t want to create a false impression that they’re trying to dishonestly profit from a refund by keeping that stuff.
- Should their account get suspended as a result, they’d consider a lawsuit, and probably class action, by communicating with other players in a similar situation, probably on Reddit, including the official Crossout Reddit channel, as well as other social media services, to find the most players they could get, for a nice, big, and very public lawsuit.
Doesn’t matter how immune Gaijing or Tard’em may feel to international lawsuits, sitting behind that big and strong Iron Curtain (while pretending to actually be based in Hungary, also with an office in the Cyprus for tax reasons). The publicity alone would be reason for concern. And, seeing as they do have those offices outside of Russia, that makes them vulnerable to international lawsuits they couldn’t ignore - as they probably would try doing if they’d have stayed based in Russia. Both Gaijing and Tard’em should be subject to Hungarian law simply due to having offices there, especially that those offices pretend to be their main centers of activity.
Ultimately, ask yourself this question: do you feel being bullied by Gaijing or Tard’em by them going back on their implicit promise of 45 levels by the end of the Radiance event? Are you going to stand up to bullies, or do you want that Omamori so badly you prefer to pay a little extra to get it? And again, I’m not recommending you do a refund of the Radiance BP . It’s up to you to decide if you’re a person or whatever Gaijing/Tard’em consider you to be.
I’m focusing on Gaijing in this comment, because I assume it was the publisher’s decision to turn Radiance into a scam. Some of the developers have intimated, in at least one live stream before an update, that they have far less control over the game than they’d want. But then why would the developers lie to us on so many occasions over the years? Is that part of their contract? Also, who really owns Crossout? Is Tard’em only a front for a roster of easily replaceable developers, who are actually employed by Gaijing, but it’s supposed to be a secret? As we’ve found out from various sources, a number of developers were replaced some months or years ago, to the point of calling it a new development team, at least in a recent Q&A that Goth Princess Yuri did. And which I still need to post here.
BTW, it’s funny how they didn’t even try to avoid legal trouble by giving us 2 challenges a day with ANY amounts of XP rewards, even 1 XP per challenge. The could’ve done 2 x 300 XP per day and call those ‘bonus challenges’ for anyone that missed some, in case they don’t actually stack (I wouldn’t know, as I did each of them before the daily refresh).
but free stuff is free stuff, I’ll take it!
