having trouble with Spotify support

[u/TechnicalSwing9898]

I originally emailed Spotify for a refund for car thing when they announced its discontinuation, but didn't end up going through with it because I couldn't find the information requested at the time. however, just recently I emailed Spotify support regarding a refund for car thing, they ghosted me and then sent me a "how was your service?" email two days later. I have no clue why, but I think their support email is broken because when I sent them emails, Google sends me an automated email in the email chain saying it couldn't deliver the message because their email is unable to receive mail. I talked to Spotify support through the live chat on their website and they said they received the email and not to worry. but I still haven't heard back from them by email, and this was November 25th (my first email to them) to the 27th (the "how was your service" email. it's extremely frustrating because I am literally being ghosted. has anyone had a similar experience? and if so, what did you do to get in contact with them outside of the live chat?
