ISI Mark - Has it become a tool for cheating consumer

Part III - Packaged drinking water in 250 ml PP Glasses

Today in a family  function, guests were served packageddrinking water in 250 ml PP Glasses. Click on the image to see the marking details. Batch No, and Packing Date are not marked. I checked thecardboard carton also. It was blank, no information printed.

Is this the way licensees are allowed to market PDW with ISI Mark?

Manufacturer has declared shelf life as 90 days from date of manufacturing. WHICH DATE OF MANUFACTURING? Also, had BIS ever checked and verified this shelf life as declared by the manufacturer?

I also visited BIS Website. Variety covered (at S. No. 36 of List of Licensees for Delhi) - 20 litre PET Jar. When I clicked on this a page was opened where variety covered is litre PET Jar and 250 ml PP Glasses. Which is correct? 

No batch No., no Packing date, this is how manufacturers market drinking water with ISI Mark without testing and hide production to save on MF. BIS officers take bribe and turn a blind eye. The are not even bothered that such untested drinking water is a health hazard for consumers.
