Vanaik Furniture & Mattress In Brampton

I purchased my whole bedroom set from them. They promised to give all ashley furniture with 5 years warranty on all the products. but the railing of the bed broke down. it also had a sofa with recliner which they claimed had a warranty of 5 years but when this sofa showed signs of again within a few months of purchase and the stitches started coming off, I went to them and even e-mailed them the photos. But of no avail. I went to them thrice to get them repaired. Finally on my fourth visit they told that the sofa is out of the purview as it was not from Ashley and moreover came with a limited warranty of one year (which the salesman claimed that it had a warranty of 5 years!!! a big jhooth of these people). Till the time I am writing the review (on May 4th, 2016), it has not crossed year of delivery, they have not contacted me nor have taken any pain to repair my stuff. when I went to complain about the jhooth the salesman told me, the manager replied that they cannot control their salesman. It means they have given them full freedom of telling as much jhooth possible just to sell their products. I have virtually wasted my money on inferior and fake quality. I will never ever recommend anyone to go there. What these salesmen promise, all is a flat safed jhooth. Is there anyway I can sue them?
