Pathetic Customer Service

I bought 8x6L Parmalat Everfresh UHT milk from PnP in Howick. When I proceeded to open the cap, I found that it virtually impossible to open it normally. After several attempts I just inserted a sharp knife and removed the cap and locking mechanism as they could not be separated. I did some root cause analysis and found that the cap and locking mechanism to be installed incorrectly during packaging. I inspected approximately 8 boxes and found this to be the same. My wife wife inspected a few more - same issue. I called the customer care line. Spoke to Carl. After listening to my complaint, Carl asked me to take photos of ALL non compliant boxes inclusive of the printed data and forward this to their what's app line as they need to investigate every non-compliant batch. I sent pictures of 5 boxes. I wasn't being paid to problem solve for Parmalat. I stated quite categorically that all I needed was for them to uplift the product with sub-standard packaging and replace with boxes that have caps properly and correctly affixed. I did also explain that I did not have my receipt as I had discarded it. He advised that in future that I should take photos of my receipt. WHAT **** ADVISE. Rather that honour my request, Parmalat have sent me a R50 voucher when I next purchase their products. REALLY - so fifty bucks should compensate for the daily inconvenience. Parmalat - wake up and smell the coffee. You DO NOT address the symptom, but you FIX the problem. I don't need you R50 discount, I need my milk exchanged. Period.
