Fork bent on a flat pack bike - what to do?
Your bike (27.5 Orkan 21 spd. MB) sells for less than US$150 and is shipped flat packed. This puts it firmly in what we call BSO or bicycle shaped object territory. 

At US$150, it’s hard to find a repair that isn’t going to cost half as much that the bike is worth. You might have the best success going to a bike coop and finding a used fork for $10-20 (or free) and learning how to repair it yourself.

Or you could just donate the bike to the bike coop and they’d use it for donor parts. Or give it to someone as a project bike. The reality is that to get to the US$150 retail price point, the bike is value engineered to the hilt (likely $50 total landed) so is built with the absolute cheapest components and as a result isn’t  worth much. The reason amazon refunded your money is that the shipping back to them is more than the bike is worth.
