I was sold fake Apple EarPods

Hello, today I went into a target to buy a pair of Apple EarPods. I bought them and went home, after opening them I noticed some inconsistencies with the assembly of the headphones (also the carrying case was scratched up) Upon a sound test I can assure you that these are not legitimate. There is a combined assembly mold that is not present on what I can verify are legitimate Headphones. The Mic is too hard to press. And the plug that goes into the phone is too large and the vents on the bottom are not real. And finally, there is a logo or print of some sort that says HTP on the junction for the wires.

the one on top are legitimate (they are the ones I had before)

pair on the bottom are too thick (pair on top are real)

I have proof of purchase, where do I go to return these?

Also I want to know, HOW WAS I SOLD FAKE APPLE HARDWARE AT AN AUTHORIZED RETAILER?
