Complaint

I bought a wall unit and a coffee table a Lewis Athlone a year ago. This unit is made of three units.Last year One unit was exchanged and the coffee table for manufactures fault. This year again I complained about the coffee tables and the unit is having the same problem. The store says it is out of warranty whereas I'm currently paying insurance on my furniture. I'm paying my monthly installments and insurance monthly but my furniture has faults I can't enjoy looking at it falling apart.
