No response after complaining about bad tasting product

Logged a complaint a week regarding the taste of coke from the 440ml buddies I bought. A week later and the rep has not called me back, this is after following up with the call centre and them promising me that someone WILL call me back.

I am eagerly awaiting that call, if this is the kind of customer care Coca-Cola practices then I would rather switch to Pepsi who offers a much better product at a much better price (600ml Buddy for R10.50). Maybe your product development people should visit Pepsi for training.
