Grammar fix
make a complaint
complain (formally or officially)
To say that you are not happy about something, especially to someone in authority, usually in a formal or official way.
Hear it in context
Notice where the phrase sounds natural.

In my opinion, if customers are unhappy with a product, they should make a complaint so the company can improve its service.
Fix the pattern
One small grammar move makes it sound right.
Not: I want to do a complaint.
Say: I want to make a complaint.
You MAKE (or 'file/lodge') a complaint — not 'do' one.
Which sounds natural?
Tap the one a native speaker would say.
'Make a complaint' is natural; 'lodge a grievance' is very formal/legal (though 'lodge a complaint' is fine in writing).
