I went to the Argentina -Belgium match, and for a lot of matches before during the past two years, and I am very happy with this website.
I always get my tickets, the seats are usually good, depends on the category I choose and the price I pay, but generally from my experience - it's a very good website if you can't buy from the official organizers.
I bought from this site tickets for the French Open - Mens & Womens in Paris last month, and i had no problems.
The tickets were delivered to my home, the service was very nice, friendly and useful.
I already ordered tickets for the next game...
