Query: It just fell apart

I purchased the Air King fan and had it for 2 1/2 weeks. It worked well during that time. Then ... it just fell apart. The motor is mounted on the back grill and several of the welds that hold it in place broke. It is unusable and unrepairable. The seller, S&C Greenworld Supply, told me I should contact the manufacturer, so far another dead end.
