Unacceptable after sales service

We bought a couch from Decofurn on 26 November 2023 for more than R 7500. The couch was delivered on 6 December 2023.

On 19 February, I discovered that the couch has a defect - the leather-like coating started pealing on a corner in the front. I complained to Decofrun, by sending them an email and received a case number. To shorten a long story, absolutely nothing positive has been done about it, even though I have sent several emails and had telephonic conversation with Edna, the person assigned to my case.
