SLEEPING ON A BROKEN BED FOR 3 MONTHS

IN SEPTEMBER 2015 WE PURCHASED A SEALLY DOUBLE BED UNIT. AFTER JUST 2 MONTHS OF USAGE THE MATTRESS WAS SAGGING WE REPORTED THE MATTER ON THE SECOND WEEK OF DECEMBER AND WE PAID AN EXTRA R1000 TO UPGRADE THE BED ON THE 27th OF DECEMBER. EVER SINCE THERE HAS BEEN NO RESPONSE AS TO WHEN ARE WE GETTING A NEW BED AND MY WIFE NOW SUFFERS FROM A BAD BACK DUE TO THE UNCOMFORTABLE MATTRESS. AFTER SEVERAL VISITS TO THE STORE TO GET OUR NEW BED THE MANAGER IS NOW RATHER RUDE TOWARDS US AND DOES NOT SEEM TO BE WILLING TO GIVE US OUR NEW BED.
