Bad service. No response query

On the 10 Jan I logged a request to have a couch that is still under guarantee. I got a confirming email for the request being logged. 2 weeks later I still had not gotten feedback from coricraft, so I send a follow up email, but got no response. Then we called the call centre again and git told that the coricraft factory would get hold of me, to to this date still nothing. Yesterday Monday 15 Feb I sent another follow up email and cc'ed the complaints department and raised my issues again and also that lack of service/feedback. But again no feedback. It has been over month and nothing has happened. I still have a broken couch that is under guarantee and coricraft is not bothered to honour thier contract or even bother try give me any form of customer service.
