Two drinks , Two responses from Two different companies

Recently I bought a 12-can carton of Fuji Apple Sparkling juice drink from Giant. The drinks were discounted as they were expiring in another 4 months. Unfortunately, the taste had 'expired' before the actual date. There was an unpleasant and chemical taste in the drink. Having thrown away the receipt + we tried about 4 cans to see if the whole batch was like that, I thought we would not be able to get refund from Giant. So I went to Pokka's website and emailed them this complaint, and asked to be compensated with a carton of their green tea instead. Lo behold, they replied, and were very polite and apologetic. They arranged a date to pick up the Apple drink and also delivered the green tea. Ok , I am appeased.

Another day, another drink - Bought a bottle of chrysanthemum tea at ZTP. This was their self-brewed kind. We have bought from them numerous times, as the drink was thick and cheap ($1). This time was not our lucky day though, the chrysanthemum drink was diluted - only a faint fragrance of the chrysanthemum, plus lots of sugar. Enraged, I went back to the shop to 'feedback'. The guy reluctantly allow me to change for another bottle, all the while saying that they brewed the drink for hours, hence the taste should not be diluted. The other bottle turned out to be the same, just as diluted. Still not happy, I went into the shop where all the sales assistants were gathered and chatting as there were no customers. I told them that the drink was still diluted and not that I want any exchange. Another guy tried to appease me by saying maybe they did not brew long enough. I left.. but on hindsight, I should hv argued that chrysanthemum doesnt need hours to boil for the taste to be there..obviously they cut the chrysanthemum portion or added too much water, but its not politically correct to tell the customer that. Hmm... still very unhappy over this incident. Definitely will boycott them.
