Bigbasket.com — insects in lettuce

Hi. I ordered some lettuce, which were delivered on time, but i found green insects inside the lettuce. It looked great on the exterior, but as i opened a few layers i saw the bugs. It was a very unpleasant experience. I would like to be assured it would never happen again. May i request you to add a customer review section on your app, so i can see ratings while buying? It would be great. Thank you.
