2012 Ford Focus Electronic Stability Control Esc Service Brakes Problems

I HAVE A 2012 FORD FOCUS SE WHICH IS STILL COVERED UNDER MY 70,000 MILE WARRANTY. I HAD PROBLEMS WITH MY TRACTION CONTROL SYSTEM WHILE TRYING TO GET OUT OF A PARKING LOT. MY REAR BRAKES AUTOMATICALLY LOCKED UP CAUSING ME TO BECOME STRANDED DURING A SNOW STORM. I WAS STRANDED FOR 5 HOURS BEFORE ABANDONING MY CAR AND FINDING A RIDE HOME FROM A COMPLETE STRANGER. THE NEXT DAY I HAD MY CAR TAKEN TO THE NEAREST DEALERSHIP AND ASKED THEM TO LOOK INTO THE PROBLEM. A DAY LATER I RECEIVED A CALL SAYING THAT THERE WAS NO PROBLEM AND THAT THE ISSUE WAS EXTERNAL, WHICH IS IMPOSSIBLE BECAUSE NO ONE HAS EVER DONE ANY WORK ON THE CAR OTHER THAN A FEW OIL CHANGES. THEY RELEASED THE BRAKES AND I PICKED MY CAR UP ONLY TO FIND THAT THE PROBLEM HAD NOT BEEN FIXED. THAT SAME DAY WHILE DRIVING HOME WITH MY WIFE THE REAR BRAKES LOCKED UP AGAIN, CAUSING MY CAR TO FISH-TAIL AND IMPACT A WALL. THE DAMAGES WERE RELATIVELY MINOR, BUT THE AIRBAGS DEPLOYED AND NOW MY CAR IS INOPERABLE. I KNOW THAT THIS ISSUE WAS CAUSED BY THE MALFUNCTIONING TRACTION CONTROL SYSTEM. *TR
