I've cancelled Netflix a couple of times. What actually got me back is the fact that they didn't inundate my inbox like some services and stores do. I mean like one email every couple months. There are some stores I get at least half a dozen a week.
They also didn't pull what XM/Serious do and make it nearly impossible to cancel. 4x 40m phone calls, then all I wanted to do was drop one of 3 radios when I sold a car. After the third call drop after a 40min hold time I cancelled the entire service. If I ever use them again, it will be a disposable single use cc #.
In the end, 2-3 streaming services is all I'm willing to pay for. More than that and if rather pirate just for the usability aspect, let alone the costs.
