Quality of Goods bad

I bought a base and mattress about 3-4 months ago at the Comaro Crossing branch. On the slip it stated Sealy but on the mattress it states Rochester and I did not think much of it. Anyway in the last 2 weeks the springs cut through both sides of the bed (material) so you actually injure yourself getting on or off the bed. I bought the bed thinking I would get at least 5 years out of it - needless to say it only lasted almost 5 months. I am quite disappointed as the branch also closed down so I don't know where to complain!
