Makro selling products that break within two weeks of usage.

I Would Give them 0 stars if I could.Bought a headset from them and the headset fell apart within 2 weeks of usage. I sent the headset back and waited for a response while I was waiting, I called Makro's Help line and when they answered the guy was singing and laughing and taking no notice of me.I called thrice and the same thing happened, eventually after the third try I got someone who could assist me. Now makro is telling me they cant repair or replace my headset as "Warranty void physical damage by end user",if the thing breaks within two weeks of wearing it how could I of caused the physical damage..Makro stop selling old and broken stock.
