Amazon FBA Fee Scam – Package dims

Per the title, has anyone else experienced amazon measuring your products with the completely incorrect dimensions? I know they say they use a special machine to get the dims but I just dont think its accurate. for a product measuring say half an inch in height, amazon is putting 3.5inches… and even when requesting re-measurements I am getting the same BS dims. I have changed my product packaging now for future listings to not be in a polybag to prevent any potential sag but even with that I am very worried I am still going to be taken advantage of by Amazon. Even for a polybag i dont even know how its possible they got 3.5 inches… i think its a class action waiting to happen but whatever.
