I asked for refund, but nothing from author

Hi was asking a week ago for refund, but no response from author and nothing from evanto, so iwas asking to now where can i contact evanto for explain the problem, i buy a lot of stuf, and if i have no support from what i am asking i will use an another site, and make complaint

Envato support: http://enva.to/help
Explain the situation, and include the fact that the author has not responded to the refund request. They will review it (typically within one week).

thanks a lot

You need to learn the correct speach on Envato at first!
