Reliance Fresh — Purchase lost at store

I purchased 2 kg of Idly Rice from Ambattur OT store along with other items and while transferring the items into my bag from the store's basket in front of your security staff, I missed the 2 kg Idly Rice packed in a brown bag inside the store. Later when I returned to the store to look for my purchase after couple of hours, I was told by your staff that the item was not found in the store and was refused a further search for the item I lost in the store.
