This piece is 99% hot air.
A bunch of backhanded attacks on Amazon before we hear the real problem, which is obviously that some automated system mis-classified the customer. Even the author acknowledges this.
I would assume a quick email or phone call with Amazon would have cleared this up.
It was a waste of time to write this and a waste of time to read it.
Non-disclaimer: I have no affiliation with Amazon except as a normal customer.
