You had to know that if you bought that package only your king level up and not your base of course…
To not forget that +5 king levels increase both Hero and Tent if we wanna intend also this, but to level up your base doesn’t exist package but only willpower on do it
Also if you lose 20K skulls during War Season, it’s not your fault if other alliance’s members attack you continuously…instead for this you should improve your base so they can win less skulls if your base is enough strong against enemies players.
But losing skulls in wars has nothing to do for your “gain” of +5 king’s levels…
I really don’t see the problem, you did a good purchase !
Moreover, decreasing the king level (thing impossible to do it, even if you contact the Support, they aren’t able to do it) it’s a real self-harm, one day you will discover that what you did was a good choice and once you will be at high level where reach the max level 120 (currently) it’s a real extremely “mission impossible”, you will congrats with your-self for what you did
Many player would like to get +5 king levels, but unfortunately seems that it appear during only at low-mid game play-life (someone correct me if i’m wrong).
