Xbox Elite Series 2 Broke twice because of the same issue

3 months ago I‘ve purchased a Xbox Elite series 2 i used it for like 2 month and played Fortnite competitvely and my RB and LB bumpers started to register twice and some times don‘t register at all and i kept using until my RB bumper completly stop responding
and my LB bumper registering everything twice so i went on and used my guarante i got a new one and after only 1 month of using i get the exact same issue and i‘m forced to buy a new one because i can‘t switch back i saw other people with the same issue but
comm on microsoft the same issue twice in a span of 3 months i did not drop it or anything related never raged on it it just broke i would like to know if fixes are going to take place in the future because thats is juste a waste of 200£ really
