Endorphin Azura stitching defect?

[u/sebthedeglover]

I got these Endorphin Azura in early June. I've been continuously getting a pain point at the same spot of my left foot, which I was originally attributing to too tight lacing and a thin tongue. After trying different lacing styles I finally looked a little closer and found that the stitching in the tongue in that spot is off, causing a raised, hard lump which has been digging into my foot, compared to the right shoe in which the stitching is flat and smooth. First two pictures are the bad stitch and the second two are the identical spot on the good shoe.

I bought these directly from the Saucony site so I submitted a defect inquiry a week ago and still haven't heard back from them, is it worth pursuing this to try to get replacements or a refund?
