I've noticed recently that even though my iPhone (running iOS 11.2.5) has "do not disturb" mode on at night, WhatsApp voice calls go through as usual. So far, the only solution I could come up with is turning vibrations off in the sounds settings. Is there a better way to handle this situation? If not, who should I contact in this case? Apple or WhatsApp?
Thank you!

This is intended behaviour. Do Not Disturb only enables Apple's features like phone and messages. It does not affect third-party applications.
From this Apple Discussion:
If you want Whatsapp to implement the feature you need to contact them:
To provide a similar setting on Whatsapp you can close it at the desired time and turn on background app refresh which will prevent it from updating and receiving messages.
To turn off background app refresh
Go to Settings -> General -> Background app refresh and turn of Whatsapp.
To completely turn all apps of from refreshing click at the top where it says background app refresh and click off.
