i want to buy one theme but they owner does not replay me. so if i buy that theme/cms then if owner does not support me then what should i do ?
It depends if:
- the item is actively supported (most are but not all)
- what the support is for i.e. if it is within support policies https://themeforest.net/page/item_support_policy
Before purchase item you can checked that item author giving support or not from here http://prntscr.com/ld235u
