How to refund ?
You answer negative to all my requests !!!!!!
Most of your questions were about theme customisation and you will not find any other theme author providing these services for free. Other questions were about theme configuration, and answers are in the documentation that I've attached. Please let me know if I can do anything else for you.
In any case, you could try asking for a refund but consider that a refund request should meet some requirements: https://themeforest.net/page/customer_refund_policy
