Terrible Parmalat

Bought a six pack of Chocolate flavored Steri-stumpie from Checkers. Opened the first one took a big sip and found it to be rotten. Basically threw up. Decided to call Parmalat help line to inform them off this. The expiry date of the product was only the 14 of June 2022. This all happened on the 20 of January 2022. They thanked me for the call and arranged a courier to come collect the products so that they can do tests on the product to see what went wrong. They required me to take pictures of the products to confirm. They collected the products. About two weeks later I got a message that let me know I have received a voucher for R20 rand off my next Parmalat product purchase, I bought six Steri-stumpie at R70 so this fixes nothing. I then called again to let them know that this was not good enough. They informed me that my call was being escalated to head office. That was over a month ago and still nothing. They are a terrible company when if comes to customer service and I feel like they did not care that there product caused me to be physically ill. No feedback, no compensation for my lose, no nothing, awful awful awful. Will never use there products again and am telling everyone I can my story so that they can know how Parmalat treats and cares for there products quality and their customers.
