Is the bottled water turned on? If it hasn't been opened, the manufacturer should come soon. You can also complain to the Food and Drug Administration.

If it has been opened, unless you can prove that the bug was in it before it was opened, but this is very difficult and there is basically no way.

When you take water in the future, be sure to check it yourself and ask the water delivery man to get on the plane for you. After getting on the machine, ask him for the security code. The security code is important evidence and will be used when complaining.
