I placed an order with order #[protected], which included a product surf excel detergent powder of 5kg however they deliver only 500 gms. The invoice which I received also says 500 gms however they charged me price of 5 kg. Even though I complaint multiple times, they denied saying it was 5 kg. which does not make sense. why should I say wrong... they should at least think this way that when a customer who regularly orders, why should they do wrong complaint. A serious action is needed since to me as do not will to fix my issue.
