World of Tanks

k so i missed the first mission cause of i dont know whu so i just left it thinking that it would fix itself but for the 2nd mission i finished it 15 hours before it was due so i left it till the next day and now it said i missed that quest and i finished the 3rd quest last night but it still has not registered so im thinking i may have entered the wrong username if so could you switch it because i finished all the quests but either a or b happend A: the game did not register that i finished the quests or B: I entered the wrong username and it was my fault anyways my username is bennnyboi2 so if i did enter the wrong one could you switch it
