Disgusting after customer service care!

In December of 2020 My mom purchased two beds from a Lewis store in Stutterheim in the Eastern Cape.Unfortunatly one of the beds had a factory fault,the mattress squeaked, u could actually hear the springs when turning.She reported the fault within less then 7 days that she was not satisfied with the bed and would like to take another one.In January she was asked to go pick another bed and cancel the contract she had of which she did. My mother unfortunately fell in and was hospitalized and was not in a state to follow up the bed matter. In a week of her hospitalization as her daughter worried that the bed would be unreturnable should a long time pass I visited ther store to inform them of the issue at hand and to tell them I would handle my mothers affairs. Store manager at the branch had absolutely no care nor any after care customer service very arrogant bare in my my mom is being debited for a bed that she is not satisfied with and is it no lose to the lewis store as they are receiving the money.To make matters worce I escalate to customer care head office and the lady who assisted me named Pam ( Ref 710945) was so disinterested in all I had to say about my mother nd the situation I was facing, her final words were that thy will call my mom so she can give permission for me to handle the matter, for crying out loud she is ill and unable to talk!!! This is very frustrating as I have been sent from pillar to post at some point I was asked If the house was fumigated, every time I try follow up a different story rises.It has been two months full trying to follow up on this and my fear is Lewis store refusing to take this bed back.
