Spotify reverted my account to their free, ad-based subscription without warning. A week later they sent a very basic and dismissive email telling me they no longer offer the service I've used for 10 years. They then continued to charge me until I noticed and complained. They refunded me but didn't apologise for the error or the time I wasted trying to understand what happened, just told me to sign up to their Premium service. Thanks for making me feel so special, guys! I won't be using Spotify again.
