what do you do when developer deny bug you found code example

Example 1: what do you do when developer deny bug you found

What do you do when the developer denied the defect you just found?

As a tester it is my main responsibility
to find as many defects as possible before
the production so that the cost of fixing 
the defect can be minimized and also the 
customer satisfaction is maximized. 
First I make sure it is really a defect,
therefore I reproduce the defect
then I save all the defect related data in Jira
such as the respective user story and acceptance criteria
the test data I used, the steps I follow while finding
the defect, the recordings of the execution and the 
screen shot of the defect.
then I set up a quick meeting in which I invite test lead,
developer lead and the developer who denies the defect.
During the meeting I give all the details
of the defect and explain why it should be 
considered as a defect. I try not the personalize
the issue and not to blame anyone but focus on result.
