Garg Foam House Faridabad - Fraud and cheating

I purchased a double mattress from them. During sell they told we will provide *year of guarantee and he written by pen on company warrenty card and when i found bed is bending from middle after use then he said company provide only one year warrenty so we can not do anything. When I visited their shop to talk with them then he blamed on me that i came to their shop and stole their gold chain from their neck. This is how they develop their business and this is how their rules and policy is.
