Bisleri — black object (insect?) inside the 20 liter water can

Address:

Bangalore, Karnataka

Last week i had bought a 25 litre water can from a local dealer in kundalahalli, bangalore named basavaraj. When i just started cutting the cap (the centre portion), i saw a black thing floating in the water. I left the can like that hoping i can saw it to the dealer. But this dealer rarely answers or picks up the phone, so could not inform him. The condition of the bottle/cans are also recently very bad. you call me at [protected] if you want more details
