I bought it as claimed if we study for 300days out of 365days, we get a refund.I and my little one was using it until the beginning of October, when we studied but didn’t show we completed it. After a few days as the issue continued, I contacted customer service, was told there was a fault about their system and is currently doing upgrade. Although the days I studied didn’t show complete, it still count in their backend. Asked me to come back tomorrow to see if the days changed. I came back and it didn’t. Long story short, I have contacted them countless time, due to their system problem, their don’t give me refund
