Here's my story with nytimes today. There's no cancellation button in the app or the website. There's a "chat with agent"option, but it doesn't work. So they ask you to call an agent, on the phone.
After ten minutes of being "next in line", I get to speak to someone. He doesn't let me cancel, but takes down my details and transfers to "Management".
I was seventh in line. But after 10 mins, I was eighth in line. After 12 mins, I was ninth in line. I was finally able to get hold of someone and cancel it, after holding for 25 minutes.
This should be illegal.
