Bad taste of juice

Early January 2016, I took a 5 litre fruit ****tail juice blend to Grano Passi. I had bought it in December 2015. The reason for returning it was because it tasted very bad when compared to lots of juice we buy from the same company. They took all my contact details then I waited. I returned to them on 29 January 2016 to check on progress. The lady, I presume was the manager and who had received the juice, told me that the result can take months to return. I asked if she could give me another juice to supplement the one with them as I was out of budget and the kids carry it as lunch to school. She refused then I left disappointed. On 9 February 2016 I returned to check on results. The saleslady told me she heard somebody talking about the returned report so she fetched it. The report states that the returned sample, when compared to the retention sample the taste was different. They also noticed colour variance. When I asked the lady who gave me the report the way forward she checked with the person in charge who said I have to take the returned juice? The company never showed sympathy for my family health forcing us to consume such product they also noticed tasted different.
