I would like to raise a complaint regarding the support team. They are even replying to my tickets and I am confused to which team should I raise this one. Kindly suggest me how to get the contact support for the theme forest site
It depends who you are trying to reach and about what.
If it’s a problem with a theme then you need to speak to the author. Authors use different methods but general rules are here https://help.market.envato.com/hc/en-us/articles/203039054-How-to-contact-an-author
If it’s something more general and you need to speak to envato then it’s here Envato Market Help and Support
Bear in mind that it is a weekend and due to global issues, response time may be slower then usual
May I know the timings of the support of envato team
Support Team will reply all open ticket one by one. So, they will reply you as quickly they can. Please keep patience hope will get reply soon.
