It's kinda like how you literally always find a few negative or 1 star "reviews/ratings" on basically any USB thumbdrive product page on Ali or Amazon, from angry customers who bought a 32 gigabyte USB thumbdrive, and only got 28,5 GB.
While it is kinda funny to read all of those stupid comments, it must really suck for those actual sellers, as they clearly don't deserve to get a bad rating and it's the lack of basic knowledge of the customer himself instead. However, these types are usually exactly the ones that are quick to point fingers at others and accuse everything of being a scam....
Sucks having to deal with those types.
Hope the issue gets resolved somehow though.
