Defects on a new Sealy bed, but we can't get a replacement

In January 2020, we bought a Sealy Queen bed at Sleepmaters Wonderpark in Pretoria. The bed was making a noise and we reported it to the branch. They sent an assessor to come to our home and inspect the bed. The assessor found a defect in the base and recommended that the base be replaced with a new one.

Since then, February 2020, to this day, 09 February 2021, we haven't received the new base.
