I set in 3 piece suite for repairs

This year in April i sent my 3 piece suite for repairs and till now its not back. Last month I went to the store where I bought it to query why i haven't had any communication in regards to my lounge suite because its been 3 months since they took them. I was told that a lot of furniture has been collected and sent back for repairs. So due to them not doing they're work or giving feed back atleast, now my family has to go through this winter sitting on the floor. And the worst part is that i settled my lounge suite payment last year in July when i 1st told them that the lounge suite was faulty. It took them 10 months to fetch it and now it's taking them forever to bring it back.
