9 CALL 1 MORNING 0 RESPONSE

Purchase a PS3 controller mid August 2018, The first one didn't have a usb receiver. I returned it and was given another controller. The new controller has decided to give up on me. So it was taken in on the 3rd of January 2019. I'm trying to follow up with the repairs division for feedback. I have made 9 calls thus 2 of these was to speak to a supervisor. NONE NOTHING NO ONE HAS RESPONDED. I WANT A NEW CONTROLLER NOW SINCE ITS STILL WITHIN 6 MONTHS OF PURCHASE. SIMPLE I HAVE BEEN PATIENT ENOUGH WITH YOUR NONE EXISTANT SERVICE. YOU GUYS CAN'T KEEP MY MONEY AS WELL AS MY CONTROLLER.
