Complaint about the Sealy mattress

I bought a Sealy mattress at Ted's home store in Umhlanga on the 17th of May 2024 and within a period of 10 months the springs are making noise every time when I'm sitting on top of the bed or whenever I'm turning at night. Even when my 11 months baby is turning I loose my sleep. I lodged a complaints with the stores department and Natasha said I must send videos of myself lying on the mattress when it's on the floor. I sent the videos on the 17th of March including the one where I was putting it back on the base and it was making noise as I was lifting it. She has been ignoring my emails and WhatsApp since the day I sent those videos. Ai also sent the invoices as requested by Natasha.
