1995 Toyota Previa

I HAVE OWNED MY 1995 CAR FOR 5 YEARS. JUST RECENTLY I WAS UNABLE TO START THE CAR WHEN THE ALARM WENT OF. I DIDN'T EVEN KNOW I HAD AN ALARM IN THIS CAR.THE ALARM WOULD NOT ALLOW ME TO START MY CAR. I FINALLY TOOK OFF THE NEGATIVE BATTERY CABLE AND PUT IT BACK ON AND SOMETIMES THE CAR WOULD START, BUT IT WOULD DRIVE ROUGH AND STALL OUT. I KNEW IT HAD SOMETHING TO DO WITH THE ACR ALARM, SO I CONTACTED THE COMPANY THAT MADE IT. THEY WERE STANDOFFISH AND TOLD ME IT HAD NOTHING TO DO WITH THE ALARM.I LOOKED ON THE NET AND FOUND MANY POST AND EVEN A VIDEO ABOUT THIS ALARM CAUSING PROBLEMS AND EVEN STALLING CARS IN TRAFFIC. AGAIN I CONTACTED THE COMPANY TO GET WRITTEN INSTRUCTIONS ON HOW TO REMOVE THE DEVICE, THEY BLAMED MY CAR AND THEN TOLD ME THEY HAD NO INFO FOR THE DEVICES SERIAL NUMBER THAT I GAVE THEM. I EMAILED THEM PHOTOS OF THE DEVICE AND HAVE NOT HEARD BACK FROM THEM. I ENDED UP TAKING THE CAR TO MY MECHANIC AND HE REMOVED THE ALARM AND NOW THE CAR RUNS FINE. I AM VERY CONCERNED THAT THERE ARE MANY PEOPLE OUT THERE THAT ARE IN DANGER BECAUSE OF THIS ALARM. LIKE I SAID I HAVE OWNED THIS USED CAR FOR SEVERAL YEARS AND DIDN'T EVEN KNOW IT HAD A ALARM, AND ONE THAT COULD BE POTENTIAL HAZARDOUS. THE COMPANY IS EITHER NOT AWARE OF THIS OR THEY ARE PURPOSELY GIVING ME THE RUN-AROUND. *TR
