There was a glitch a few days ago when I was trying to buy a pack. So I tried writing to the customer care using the in-game option. Then continue on asking them again and again for the reply. But till now it's no avail. So probably I lost some money and the interest in the game.
Before that, I also tried to contact them a couple of times but no use.
Does it happen often? Do these customer care guys exist? Will I ever get a response from them?
