I didn't want Netflix service, though since I was gifted a month I thought I'd try it. Had to put my credit card details in for a free month I was gifted. First had to signup for the free trial month, putting in my credit card at that point. The gift month wasn't added. After 2 or 3 phone calls to Netflix support, and over an hour later the second month was added.
I had asked and was promised that I would be getting an email letting me know 1 week before that the renewal period was approaching. No email ever came of course.
Might seem small, but doing these kinds of tactics on a large scale, with tens of millions of users - they know the recurring rate will be higher, and many people will keep getting billed without remembering or realizing, even if it's for 3+ months. It's dishonest.
There are other minute details I've not written out because I don't care to put the energy into it.
