Crack under the screen of new Venu 3s

Hi 

I was gifted a venu 3s as my first garmin a week ago and yesterday was looking at it in the sunlight and realised there is a straight crack like under the glass. I can put my fingers on it and there is nothing there but can see it in sunlight or in different angles. 

I have been so careful getting used to it and like it's the most expensive thing I own currently. 

I'm pretty upset that a week in it looks like it has this crack. 

Has this happened to anyone else before? Does Garmin help?
