Gonoise.com — go noise shots x5

Go noise service is very poor there is no good means of communication to service center they provide this number [protected] and nobody have picked my phone only bell is ringing and they mail me that I have self shipped my product to their service center and also they will not reimburse the shipping charges which they mention in their sites that they will reimburse such expenses
In my go noise shots x5 they got automatically disconnected and even if they connected it sound automatically got off even if song is playing
I want to replace it .It is under warranty
