I don't think anyone assumes when they take the cheap shipping option that they are eating a 10% chance the package never shows up. Nor mis-matched packages. Nor sudden calls from collections. Nor being re-labeled in the database as a 'distributor.'
Author gave time for them to work out the bugs between each attempt, and, seems each attempt went worse.
Classic post-2010s-era support quality.
The fact that it took this customer so long to decide he hated the company indicates that he is quite patient — other customers might have changed their mind about Mouser sooner.
did you not read the article? the problem was items just disappearing entirely and Mouser being dicks about refunding or reshipping things that got lost.
The only difference with cheaper shipping is that it should take longer to arrive. That's not what happened here.
Our customer support people have access to know where any order is and if it has been split across multiple shipments. At the very least, we know if the box left the warehouse.
