Bad Coke

<p>I have purchase a 1 L coke today. When i opened it no gas at all. The seal of the cap did not even brake. I have also purchase a 500ml last week and could not get the cap open after I have used a plier to get it open no gas at all. I have heard of lot of people complaining. Coke is so expensive and to get it like this. What is going on.</p>
