garmin no longer supports my c330 sold me updates for life i'm not dead 1200E.151st street Olathe,Ks 60062 WORLD WIDE

BOUGHT GARMIN C330 ABOUT 7 YEARS AGO. I WAS BUYING MAPS EACH YEAR. ABOUT 2 YEARS AGO GARMIN HAD MAPS FOR LIFE FOR MY 330 I PAID 89 DOLLERS. NOW  I TRIED TO UPDATE MY MAPS NOW MAP UPDATE NO LONGER SUPPORTS MY C330.CALLED GARMIN THEY TOLD ME I HAVE TO BUY NEW UNIT THEY WOULD GIVE ME 20% OFF.THIS IS BS I WILL NEVER BUY A GARMIN PRODUCT AGAIN. THEY HAD TO KNOW THEY WOULD END SUPPORT FOR MY UNIT. THEY SHOULD NOT HAVE SOLD ME MAPS FOR LIFE. THE UNIT IS ONLY 7 YEARS OLD I COULD SEE IF IT WERE 20 YEARS OLD. I PAID NEARLY 300 DOLLERS THEN FOR THIS UNIT. IF WOULD HAVE KNOWN THE UNIT WAS ONLY GOOD FOR 7YEARS I WOULD HAVE TOLD THEM TO PUT IT YOU KNOW WHERE.THE UNIT WORKS FINE I HAVE ALL MY CUSTOMES LOCATIONS ON THIS UNIT OVER 100.THIS IS A MAJOR PROBLEM FOR ME.
