Lewis stores dissappointment

I opened an account with Lewis stores on the 03/10/2023 bought a bamboo bed and a sleigh headboard.

In the past few months I have noticed the mattress is uneven and makes squeaky sounds when climbing on or off the bed. I have reported it and the feedback I received was that I need to pay R1900 to get another mattress because they told me my warranty is over. I feel it is not fair as i did not expwct the matress to last me only 1 year. A gentleman from PE came to inspcect and saw that my bed is still in good condition however there is a slope in it and heard the noises it makes. i am not happy at all as they can see i pay my account on time every month and have never been in arrears. this is such a disappointment because i was advised on a bamboo bed being one of the good brands and the person who gave me the advice has not had these problems with their mattress.

I feel as though this could have been a demo mattress given to me.

Please note I am a single woman, do not have boyfriends and kids that could be jumping on the bed.
