J K Cement - Bad quality cement ceiling leakage because of JK Cement

JK Cement was suggested by Mahajan agency, Khatima which was said is good option in ceiling construction dated **.**.**** but as the rainy season arrived my cieling has started leaking with all the parts of cieling being heavlyn dropping up water and their is no support from the JK Executives and agency person. This has affected us mentally because our hard earned money was invested and trust is breaked with agency owner and cement company. We have been trying to stop leaking but their is no help from Company . Also because of this my house construction has been hampered which is leading to wastage of other construction material. Kindly take appropriate action on the same .
