Please help. I'm not getting HOMM VI Complete Edition in Uplay.

When trying to activate this game in Uplay, I'm not getting 'HOMM VI Complete Edition' at all. But just got only 'HOMM VI Shade of Darkness' instead (which I already have) with unknown reason.

Now I have two duplicates of 'HOMM VI Shade of Darkness' in my Uplay games list (see the attached screenshot URL).

Could you please help me to refund this product?
