Warranty replacement of Inspiron AC adapter

I have an active case on an Inspiron where the AC adapter has an intermittent connection between the AC cable and the AC/DC adapter body.    It has been flaky for some time but has recently prompted me to put in a warranty replacement request before I get to the 1 year anniversary.    The support personnel seem insistent on making this a wear and tear issue when clearly it isn't (the adapter just lies there all the time, no stress is imposed).   They have twice pointed out that they would gladly replace it if I had Complete Care on the laptop (damage, accident coverage).  I have replied that this is completely unacceptable and they need to re-evaluate this response, but I want to know how I can file a complaint if they maintain course.   Thanks in advance for any council I could get on this matter.
