In-game purchase bug

Yesterday i tried to buy 2 USA tech tree packs on summer sale, but the transaction got declined and the error without code popped up(look at screenshot). I thought that it was just an error but when i checked my bank accout, the money were withdrawn from it and i didnt receive the vehicles. What do i do in this situation and how long could the resolution take?(i need to resolve it before summer sale ends)

Hello, i have done that, but is there any faster way to do this, because from my experience this problem could be unsolved for weeks and a lot of support contacts, and i need to buy these vehicles till the end of the summer sale, what could i do to make it faster?
