I hate this type of opening anyway. It sucks. You never get enough of the liquid out, yet you can hear it jangling around inside, taunting you. I buy a coconut water that has this type of container and I need to take a hacksaw to the container just to get all the juice that I paid for. Please tell me that you have the same issue. If it was water it'd be one thing, but this is sweet coconut water we're talking about.
When you get a product that is messed up like this it is always best, and customary, to drink half of it and then return it. Might as well get a few good sips in before you get a new one. Just tell the store that you didn't realize it was broken until after you opened it. See? I'm a scamming genius.
