Pick n Pay customer care is appalling

Pick n Pay customer care is appalling. I asked them to assist me with their in-house brand sweeteners which had sealed empty packs...they have been sending automated responses for the three weeks say "your request has been updated". I dont need my request updated I need my refund or replacement. Clearly there is a poor quality check for your products and now you cant deal with a complain its disappointing and quiet frankly upsetting and annoying how you are treating this simple issue. I didnt get the product for free I paid for for it, I need a replacement or my money back not half baked responses.
