I ordered gre plus toefl course for one month. Marketing department is there to sue the people around. The very next day when i asked for refund due to some personal reasons... They told they will give refund and despite calling more than twenty times, they told that it will be refunded in 23 days and request has been raised. When i called after 23 days, they blocked my number. I was not able to reach them. Also, i messages md of greedge in facebook, he didn't even reply. Such a bad service company is there to sue the people.
