Good evening.
I have a little problem.
I bought 1 Lina Battle Caster Set but i got 2 and i payed for 2.
But i am sure that i pressed the buttom only 1 time.
Should i contact steam support or Valve dont give the money back?
I am 100% that i pressed the button only 1 time,so i think it is a kind of Dota 2 Store Lag or something like this.

Ps Sorry for my English.
