I am disappointed in a Restonic Matrass that I bought a year and 10 months ago.

We bought a Restonic Conoisseur 152cm bed set at Lewis Store in Colesburg on 1 July 2024. It is not 2 years later and there are noticeable body impressions, sagging and lumps on the matrass. At Lewis the manager said there is only a one year guarantee and no warranty . because we bought the matrass cash. That is not acceptable! I send a message via facebook on 23 April 26 and got a response , that said it is not their standard they hold themselves to. They promise to look into the matter and asked me to send details and plus photo's etc , which I did.Nothing happened. Then I tried Restonic SA on whattsapp on 22 May and start start talking to a robot. I was asked again to send all the detail plus photo's, which I did. I was asked if I wanted to speak to a customer care consultant and I choose Yolanda. The response was: Thank you Alta van Niekerk, we will assist you shortly. On 26 May I wrote a message to Yolande and got the same response. On 28 May I send Yolanda again a message. Response was that the matter was hand over to Fortunate , who word with complaints for Lewis. I am still waiting for a response from Fortunate and today it is 5 June 26. I thought Restonic SA is a respectable company and proud of their product. So far it doesn't look like it. I think a refund will be acceptable or, a new matrass! Alta van Niekerk , Cell ***
