I experience continuing problems with Amazon.
1. Their delivery people are incompetent. Cannot even read. I post instructions at my door as to where to leave small packages that they completely ignore. Just leave packages out on the step, in the rain, for porch pirates to grab.
2. There is no place to complain. My letters to corporate go unanswered.
3. They trick you into signing up for "Prime" at checkout. I was tricked, immediately canceled, yet they tried to bill me. I had to file a complaint with the Washington State Attorney General to get them to reverse the charge.
Dealing with Amazon is worse than dealing with the government - even the IRS.
