Restonic advise me to put velcro on base and matress to keep it from slipping of the bed

I BOUGHT A RESTONIC BED FROM RUSSELL'S. THIS MATRES SLIDES FROM THE BASE OF THE BED ALL THE TIME. MY 3 YEAR OLD NIECE CAN MOVE THIS MATRES FROM THE BASE. I BOUGHT THIS BED AND IT WAS DELIVERED 3 DAYS BEFORE I WENT INTO LABOUR WITH MY NOW 3 MONTH OLD BABY. THE SECOND NIGHT OF BEING AT HOME I ALMOST FELL OF THE BED THINKUNG IM SITTING ON THE BED WHEN IN ACTUAL FACT THE MATRES WAS HANGING OFF THE BASE WITH MY NEWBORN BABY IN MY ARMS ALMOST LANDING ON THE FLOOR! I HAVE CALLED RUSSELS WHO THEN MADE CONTACT WITH THE REP. I GOT A CALL FROM A GENTLEMEN WHO SAID HIS MANAGER AT RESTONIC WILL CALL ME... IM STILL WAITING. TODAY I ACTUALLY FELL OFF THE BED HURTING MY BACK SO BADLY IM IN EXCRUCIATING PAIN! I CALLED RUSSELL'S AGAIN AND THE SALES GUY ADVISED RESTONIC CANNOT REPLACE OR RETURN MY BED AS ITS NOT A FACTORY ISSUE AND THAT I MUST PUT SOME VALCRO ON THE BASE AND MATRES TO KEEP IT IN PLACE! WHY DO YOU NOT TELL THE CLIENTS THIS UPON THE PURCHASE OF YOUR BEDS? ISNT YOUR BEDS SUPPOSED TO BE COMFORTABLE? ALL MY HUSBAND AND I DO EVERY NIGHT IS MOVE THE BED RIGHT. IN THE MIDDLE OF THE NIGHT I HAVE TO MOVE THE MATRESS. NO MAN! THIS IS NOT WHAT YOU ADVERTISE
