Poor customer service at Sleepmasters piet retief

I bought a bed on the 4th March 2024 (cash sale) at Sleepmasters Piet Retief. On the 24th April I noticed that the mattress makes noise as if something inside is broken. I reported the matter at the store on the 26th April and I was advised by the staff to take a photo of the bed and report the matter to the manager. I therefore reported the matter to one Gift Msibi officially on the 29th April. To date no one has contacted me regarding the way forward. I find this behaviour to unacceptable and I am likely not to ever buy any product from Sleepmasters again due to this experience.
