I have had serious issues with Amazon these last two-three months which has resulted in my moving a majority of my purchases to a different online retailer.

I bought some ASSIMIL language-learning books being sold by a (known) POD firm. But I got some random (or so I thought) POD crap instead of the books I had ordered. I returned them and tried it again a month later (after confirming with customer care that I will get what I see in the listing) to see that the exact same books were sent again.

When I compared the ISBN numbers, I found that the books I had ordered were the older 978 series which can be reduced to the 10-digit version while the ones they were sending were the newer 979 series with only the check digit differing. I had to call them 15-20 times before I got my money back because they would repeatedly set up a return pickup, not do it and then claim that I have cancelled it. The books are still lying with me. They haven't bothered to collect.

They have routinely sabotaged multiple other deliveries by not visiting my house and providing bogus "OTP not provided/unable to contact" updates.

The absolute worst thing that happened was with some books I bought from a small publisher that they, unfortunately, sent by Amazon Shipping. One month and multiple calls/emails later to complain about Amazon's bogus delivery attempts, they completely ghosted me and the publisher had to RTO the books back. I talked to the publisher and they said they cannot afford to be out of pocket on shipping, so I paid them INR 1,000 to cover their expenses for the unnecessary two legs of shipping.

I have now decided that I am dealing with absolute scoundrels who do not value their customer's time and plan my purchases accordingly.
