Too Ashamed to give feed back

I went to Jamaica in Boksburg , where like usual I buy my Glaceau vitamin water (2-3) cases of water . I placed it on HelloPeter before , a few months ago already and still got no feedback , they sell expired stock and put it back just so they can sell it to another customer who dont check the dates .. This is unexceptable , How can I go buy there again , cause alot there is expired .. Will they ever give feed back or should I tell every newspaper how they operate ?
