Greetings,
today (apprx. 9:05 a.m. CET) I have bought Valor pass for 299 Kč (crowns, Czech Republic) while the problem with not showing daily quests was in place. After the update the price was 249 Kč.
I posses all the necessary documents (time, transaction details, number of order) if it’s required.
I am from Czech Republic too, but I haven’t seen different price than 299,- This price was there at the beginning (9am CET) when they had issues with daily trials and the same price is there even now (I haven’t bought Valor pass yet).
But if you think something is wrong with your payment you should contact game support, you probably won’t get any help with such problem here, forum is mainly driven by community.
