Rejection of warranty claim Asus Bluetooth headset

I bought an Asus Bluetooth gaming headset from Wootware and had to bring in my faulty unit to Rectron Midrand. What happened was that after a few months of use, the clip on the side broke due to faulty workmanship and I had to to tape it up. Nevetheless the unit worked fine for a few further months. The Asus Armory Crate useless software notified me that an upgrade must be done so I plugged in my headset to my PC and updated. After it the unit was bricked. The power light came on but did not operate. This is through the official Asus software. I took in in to Rectron and after constant waiting for emails to be rep**** to, they advised me that the unit would not be replaced due to it being broken by myself. This is bull****. So I told them just to fix it as it was bricked but they stated that they do no cover any software related issues. The manager at Rectron tried to see if it could be fixed but mentioned that he suspected the power port was damaged where the clip was broken which is also incorrect. So from a faulty and failing product, to terrible customer service, then finally to a warranty claim being rejected and blame placed on myself. These are the worst companies I have dealt with be warned.
