POOR support and poor service

Purchased a Razer Tournament edition headset last year April ( at that stage it was selling for R2700 ) The cable broke and it is still under warranty. I requested a return but got denied and their reason is that I inflicted damage and broke the item myself and thus won't be getting a claim. Their service and response has been poor of the start , the person who sent me the email has not contacted or even rep**** to any off my emails. I only received the initial email and that was that.
