Coca-Cola

I am not happy with the Coca-Cola I bought recently, There is some oil, soap tasting substance in the sealed coke bottle, it was not just the one, I only realized it once I started drinking the coke there was something wrong, then I went to the fridge to discover this stuff floating on top of a sealed bottle coke.... I had some food poisoning afterwards.... I am a big coke fan but this really put me off
