Disappointed the the 7 point Hub Not Working after 4 months

I purchased Plugable 7 Port Aluminum USB 3.0 Hub (VIA VL812 Chipset with Latest 908x Firmware, and UL Certified 4A Power Supply)
Plugable 7 Port Aluminum USB 3.0 Hub (VIA VL812 Chipset with Latest 908x Firmware, and UL Certified 4A Power Supply) July 16, the product was supplied by you and full filled by Amazon. The Hub worked for 3 or 4 months and the Hub died. I checked the Power Supply with an AMP meter, that is good BUT the Hub itself is dead.
