PLEASE DO NOT MAKE THE MISTAKE I DID OF BUYING MY BED FROM SERTA

2022 I BOUGHT MY BED FROM SLEEPMASTERS WONDERPARK (Serta) ,12 MONTHS LATER THE BED STARTED MAKING A NOISE . AN AGENT WAS SEND TO MY HOUSE FROM SERTA BEDDING TO INSPECT THE BED . THE BASE WAS TAKEN FOR REPAIRS . 12 MONTHS AGAIN THE BED HAD THE SAME PROBLEM , THEN THE INSPECTOR WAS SEND AGAIN , NOW THEY GAVE ME A NEW BASE . HARDLY 24 MONTHS THE BED HAS THE SAME PROBLEM . NOW I AM TOLD TO PAY FOR THE REPAIRS SINCE THE BED IS OUT OF THEIR 24MONTHS WARRANTY. I ASKED THE AGENT TO SAY ,BECOUSE THIS IS THE 3RD TIME I AM COMPLAINING ABOUT THE SAME THING AND THE BASE DOESNT EVEN HAVE THAT 24MONTHS WHY SHOULD I BE THE ONE COVERING THE REPAIR COSTS? SHE THEN SAID THEIR WARRANTY STARTS FROM THE DATE OF PURCHASE EVEN THOUGH THE BASE WAS EXCHANGED(WITHIN 24 MONTHS). THIS MEANS AFTER EVERY 12-18 MONTHS I WILL BE PAYING FOR THE REPAIRS ? I DIDNT GET WHAT I WAS SOLD , I DIDNT BUY TROUBLE ,BUT IT SEEIMS I WILL NEVER GET THAT COMFORT I WAS PROPMISED WHEN I WAS MAKING THE PURCHASE .
