Rak Ceramics India — Toilet products

The worst product that I have ever experienced in my life. Recently I bought a new house from my relative, .He lived there for one month only, he even not used some toilets. So I bought that house for living, every thing in this house was in good condition except the products from rak ceramics. Recently I replaced one of my flush tank with new one, because that flush tank was broken with out any reason. Now I noticed another product from this company also broken. Now I am totally fed up with this product.
