I know I am late, but I just want to share my thought. I was working on a project where I am writing a method. The method uses retrofit to get data from server. Since other developers in my company will use this method, I could not use a POJO class (in your example, the TrackerRefResponse class). So I used JsonObject / Object like this:

interface APIService.java

public class APIService{
    @FormUrlEncoded
    @POST
    Call myPostMethod(@Url String url, @Field("input") String input);
}

Then in my method, I wrote this:

Call call = RetrofitClient.getAPIService().establishUserSession(post_request_url, someParameter);

call.enqueue(new Callback() {
            @Override
            public void onResponse(Call call, Response response) {
                JsonObject jsonObject = response.body();
                String jsonString = response.body().toString();
                // then do your stuff. maybe cast to object using a factory pattern  
    }
// rest of the code
}

You can also use Object instead of 'JsonObject`. Later, when you will know which kind of response it is, maybe you can cast this into desired object.
