Expired Long Life Milk

Good day<br> <br> Please advise who I can contact wrt longlife milk I purchsed at your green point store I bought 3 packs when it was on special 29/01/15 my daughter got sick with cramps and runny tummy on the 11/02/15 and I had to take her to the doctor, I didn't know why, something told me to look at the date and the carton said 02/12/2014 used 1 carton which made her sick and people in the house also started getting cramps however other 2 cartons were dated 2015! I threw the slip away as I bought it end of January but if need be I can go to bank and get a statement as I used my bank card to pay who do I complain to as I'm highly upset<br> <br> My mom went to the store yesterday 12/02/15 to complain and the exchanged the 1 carton and told my mom (who is sickly) to bring a carton a day to exchange!!! HIGHLY UNACCEPTABLE!!! <br> <br> Please sort this out!!!!
