Poor service communication & poor quality of Slumberland bed by Lewis Stores

On 6th Dec '21, I bought a Slumberland double bed [base & matrass]. Less than a month later, the matrass has a dip where I lay, also a spring makes a noise when I sits on the bed. Complaint was laid, and finally in Feb I got a new matrass. Awesome. Then in July '22, my son let me know that Lewis dropped off a new matrass and took the old one. Wow, this is service I though. NOT so good news for me, since it is 2 weeks later, and I have the same problem again!!!!. I contacted the stock on Thursday 4th of August, and still he does not return my call OR give me any feedback on my query. My brother promoted Lewis Stores to me for a bed, and now I am very disappointed that I did not go to any other store/company for better service.
