Gonoise.com — Replaced my brand new product with a used one.

Bought Noise Shots Neo latest model as a birthday gift for my father.
Received product with very less battery life. Sent back for replacement and got an old pair of earbuds as replacement. Tried talking to Noise customer support but no way to talk to a real person. Tried multiple emails but got no reply. They only let you register complaint and don't communicate with you at all. Now the replaced product I have is visibly old and has distorted buzzing sound at volume over 50%. I tried replacing it again but got it as it is back and a resolution that my product is working fine. I am stuck with this useless old product. Worst support ever.
