Bad Quality products from Woolworths!!

Contacted Woolworths complaints about 6pack sugar free vanilla cokes not having any gass. Bought almost 10 6packs with zero gass some I opened and poured out because of no gass. Zero feedback from Woolworths. Very disappointed that Im now sitting with all these Sofdrinks with no gass so much money wasted and clearly Woolworths doesnt care.. have not bothered to keep slips obviously because I have always bought them and there has never been a problem.
