Very Mad!

Send it to me - I like my soda flat! :o)

Return it to the place of purchase. They should reimburse you.
You did not include the lot number from these cans either so how is
anyone to figure out how long you had these.

You could also make a phone call to them about this and like Olie
says, they may send you something too.

I still think it's best to include as much information as possible the
first time around. It allows them to investigate immediately and then
contact you with their solution.

I've been helping out this week at my company's Help Desk because
they're short staffed. Since I'm not familiar with all the systems
much of what I'm doing is taking messages and passing them on to the
two remaining analysts. In all cases, I pressed the user to provide
me with more information than a call back number.

By doing it this way, I was able to pass as much information along to
the analysts and 90% of the time they were able to resolve the issue
without contacting the user for more information. Then they could
place one simple call back to the user with the resolution. Result,
greater efficieny and happier users.

I feel the same principle applies here. The more information provided
allows for a quicker resolution to your complaint rather than have it
land in the "call back for more info" pile.
