Bad service

I received my 3 piece lounge suite on 20/03/2024, which I bought on lay-buy, but within a year it was damaged already recliner not working on the 2 seater one, log a complain via store 08/01/2025, the technician contacted me to say they will come on a Saturday, since then i've been waiting, went to the store manager he also don't know what to do, call their customer care line and it's also not helpful, I don't know what to do now very frustrated by their service.
