The story goes on to say his Amazon Prime credit card began to incur charges.
That takes it beyond “free stuff” territory.
I got an unsolicited package from Amazon, and called and texted anyone who might have sent it, but got negative replies. Then I called Amazon. The person I spoke to said it was a “mix up at the warehouse”, and I should keep it. On my next MasterCard bill, I saw a bunch of unauthorized charges to Amazon. Apparently the fraudster had had the first purchase delivered to my house and subsequent to somewhere else.
I called MasterCard, and they very politely told me to please try to rectify the matter with Amazon. Previously, all my encounters with Amazon customer service had been exceptionally positive. I explained the situation, but they refused to remove the charges. I called MasterCard and explained again (the fraud prevention agent had the history of previous call in front of her) and she removed the charges, and issued a new card. I asked if they were going to go after the miscreant. She said that she did not know, but probably not, since these cases cost more to pursue than any recovery they might make. I just wanted them to imprison the sob to encourage the others.
