Bad service

I bought Samsung Level U earphones late December and they malfunctioned in less than two weeks, when I took them back to the store since they were under warranty the manager Andrew was friendly but the lady employees treated me like I had never owned a pair of earphones before. I was never contacted about their return, I constantly had to go check; I got them back after three weeks and in less than two weeks the same problem occurred. I took them back last week Monday and I'm still waiting for their return. My problem is the quality of the product and the fact that you've had more possession as compared to me.
