SOLD ME EXPIRED INKOMAZI

I purchased DANONE inkomazi on Friday evening 15th Dec(expiry 28 December)only to realize when I get home that it is off/expired unfortunately for me my kids 3yrs and 8yrs had already ate it in my absence and both suffered runny tummies and vomiting all night on Saturday 16th Dec, I found that the maas they ate was cause, I took it back to shoprite and laid a complaint and even sent an sms to 44889 but to no avail, the shoprite store manager Zandile Mokoena then requested that the staff bring her 4 more inkomazis from the fridge to see if anything else was off and to her shock and surprise 3 of those were expired but BB dates were 28/29 December. I had to take my kids to see a Dr on a Saturday public holiday to be treated for dehydration and diarryhea which cost my husband and I R1500 incl medication, 2hours in the Doctors rooms, this also caused me to miss my cousins wedding which I had prepared for, for months to nurse 2 sick kids all because DANONE Distributed rotten/expired goods to their distributors/clients. I believe I am not the only one who bought this because shoprite fridges were full of your product on Friday evening but Saturday morning the fridges were almost empty not only are you discrediting your brand but you are dragging Shoprite in the mud with you, I am so angry in fact I am disgusted at the fact that I have supported and trusted your brand for so long and now look at what that has cost me.
