Bought Infacare but instead got sand in a box

This is just to make you guys mothers aware and not fall victim to this , shoprite and Infacare should be aware of this as I’m not sure whose more to blame i bought Infacare stage 1 box 400g at Shoprite Delft Mall everything was normal till i opened the box to my surprise the sachet was sealed with a clear tap and i still ddnt think much of it till I saw sand in what was suppose to be powder milk for a baby and no as a new mom I dnt have energy to go fight with your staff hence i opted to come here. I wish i could add pictures so you all can see the sand that they thought my baby deserved to drink. You guys should practise the same thing you do with toothpaste when 1 purchases it do the same with such products
