Reliance Fresh — quality of the product.

I feel very ashamed to report a complaint about such a big brand. I have purchased maggi and some biscuits from reliance fresh narela and i did check all the expiry dates but i think this company just change expiry date and again stack it in counters. After opening the packets of both i realized it is smelling awful and taste even worse. I have saved some quantity to show it and make it check in labs regarding its quality and expiry so that i can be assured whether it is a mistake on my behalf or otherwise.
Its a request to have quality control on all branches so that it will not defame its brand value, as well as its health consequences, can be worse. It is a customer-oriented market so consideration of their health should be its first motive.
