How to spot greedy companies and how robotization or AI helps them achieve itMy personal case with SpotifyFailing to update my credit card details prompted "You have lost access to your premium account.After 1.5 hours of dialogue with Spotify customer support based outside Sweden, they realized that I am temporarily outside of my home country, temporarily at my vacation home in Greece, and based on pinning me down to my current location, they asked me to change my home address to Greece, which I did.I added my credit card, Spotify charged my bank account in less than 10 seconds, and then I invited my 17-year-old daughter to register with my new Spotify membership, Premium Duo (not saying a word about the fact that all the communication prompted on the app was in Greek only), which failed massively due to the fact that you can't have any Duo or Family plan if any of your family is temporarily outside of your declared residence home.The customer representative told me that any member of my family could join, no matter where they are now. Big lie.But hey, it is not possible; if you are outside of the country, even temporarily, forget about it.Now I contacted them again and asked them to cancel and refund me. Still in wait.Now my daughter is 17 years old. A high school student, last year by all means, is not recognized as a student, but she can register as an adult, for which the price is almost double.Now all these Spotify barriers work against any EU core principles, and I wonder if any big law firms can investigate and eventually open a class action lawsuit against Spotify.
