Faulty product and APPALLING customer service

APPALING service. I bought a sleeper couch about 3 months ago, and within a month the leg was collapsing. I sent in a warranty claim/complaint on 20 August and was asked for the store details and my details which I promptly sent in. Since then I have tried to contact Decofurn regarding my complaint to no avail. The Facebook team keeps telling me they are escalating my complaint, and the emails are not being answered at all. It is not acceptable to wait more than a month for any kind of response regarding a faulty product.
