Deezer is not updating

I really regret paying for a whole year. I thought it would fix the many faults. If I update a playlist I need to restart my phone, reinstall Deezer and clear cache about a million times for Deezer to stop playing a song I deleted. On occasion it plays a different song from the title and my favourite tracks are not updating despite clearing cache a million times, reinstalling the app, restarting my phone etc. etc. etc.... Also Deezer seems to classify everything as pop, despite me playing mostly folk, singer/songwriter, rock, and indie/alternative pop. It's very strange...
