Product dissatisfaction

I bought the Redragon Saturn wired controller with much expensive amount than the other cheap controllers iv buying thinking that atleast it will last longer. But i was wrong the controller broke 3 weeks later after i have bought it . The R2 swing button broke the little handle inside, im very disappointed which i only play games only 3 hours a day when i gate home from work. The issue is i dont know where i can the replacements, what do i do with whole controller.
