Hello! 

The only ways to get the legacy skins are getting them from containers or buying them from the shop,
No one can know if these challenges will come back except the developers.

In the "Letter to Santa" contest they said everyone would have a chance to win, they did not say everyone would win, maybe you came out unlucky here but I'm sure you'll have more luck in other contests.

For me everything worked fine, try to re-download the client and see if it works.

Since this article did not help you to solve the problem so I recommend you to contact the Technical Support and they will help you in the best way.

You bought the Crusader hull? Even if you do not have any hull / turret, you still have the skins.
If you already have it in the garage so try to rejoin the client.
 
Update: Wait for the moment when it will be possible to buy the Crusader and then you'll be able to equip the XT skin (as @yyang_tanki mentioned above).

"Gold digger" paint was added to the game (at Tier 7 of the July 2020 Challenge B) and now you can also get this paint from the "First Purchase Bonus" offer on mobile, In my opinion as long as there is an option to purchase it now then it is not considered that rare.

The duration of a battle is 5 minutes until November 18th, at 02:00 UTC. then it will return for 7 minutes.
