2015 BMW 328XD Visibilitywiper Problems

I WAS DRIVING DOWN INTERSTATE 95 IN NJ DURING INCLEMENT, COLD WEATHER. OTHER CARS AND TRUCKS ON THE ROAD WERE KICKING UP SNOW, SALT AND SAND WHICH WAS COLLECTING ON MY FRONT WINDSHIELD. I TRIED TO USE MY WINDSHIELD WASHER FLUID, BUT WHEN I ENGAGED IT, NO FLUID CAME OUT AND THE WINDSHIELD WIPERS SPREAD THE DEBRIS COVERING THE ENTIRE WINDSHIELD IN A BROWN FILM WHICH BLOCKED 100% VISIBILITY. I WAS NOT ABLE TO SEE ANYTHING. I ENGAGED THE WIPERS ON THE FASTEST SETTING TO TRY AND GET THE FILM OFF, BUT FOR A PERIOD OF 5 OR 10 SECONDS, I WAS COMPLETELY BLIND, DRIVING ON AN INTERSTATE HIGHWAY. I TOOK MY CAR TO THE OPEN ROAD BMW SERVICE CENTER IN MORRISTOWN NJ TO HAVE IT FIXED. THEY TOLD ME THERE WAS NOTHING WRONG AND SENT ME HOME. IN THE 15 MINUTE DRIVE HOME, THE WASHER FLUID SYSTEM STOPPED WORKING...
