Hi guys, i wanted to purchase the CS:GO from the discount, but when i try to purchase it from my cart, it says unexpected error.

I tried 3 different credit cards, and still i got the problem.

I've called my bank, they said theres no problem with your credit card.

I've sent support ticket to Steam Support, but theres no answer from them yet.

If someone could help me it would be great. There's 7 Hours left on Discount, i want to buy it before discount ends. Thanks..
