Zuari Furniture — vogue king size cot damaged and no help from the company

Had purchased a zuari vogue cot king size bed from ernakulam. During the purchase was informed it has a warranty for 10yrs. Now after 5yrs there is a crack on the side railing. Trying to contact the company and the place from where it was purchased but no help. Gave relevant pictures and showed the bill but yet no response on the matter. Instead the concerned people are saying to get it fixed by myself. Then why go for such a brand... Moreover it's a furniture that i had purchased not a showpiece. A crack like this is so not acceptable.
