Babies Purity

I am immensely upset by the service and products of tiger brands. I bought my son purity, mums milk tart and apple pie to be specific. I was utterly shocked by the condition of the purity. It was watery and disgusting. We called tiger brands and thereafter they promised a R30 voucher for purity. Last time I cheaked you can only get two bottles for that price and we bought five that went bad. Eventually we spoke to the manager Mr Moodley and he said he would be sending a courier to fetch the bottles and send them for testing. Thereafter he called us back today and said there is no way in which he can help us out because one bottle that was open had baby saliva in. How do you justify that? What about the bottles that were closed and sealed but upon opening they were watery. Is this the service that you give?
