We'd like to help, Ramesh! Google Play Music offers music recommendations based on your location. You can disable location-based recommendations from here: Play Music app > Menu > Settings > Location History > turn "Location History" off.
Sorry for the trouble. We do have 24/7 support and are looking into why you've received an error on our contact page. In the meantime, you can contact our support team through a direct phone number, instead: (855) 836-3987. Hope this helps!
