Pathetic Customer Service and Product

Disappointed in Sally Williams. Purchased a large macadamia nougat bar from Pick n pay at the beginning of this month, once opened I noticed that the sides of quarter of the bar were missing. Just the thin lining was there. I messaged them on Facebook for assistance and received a response that head office will contact me (5th December) it is now the 22nd and still no one has bothered to contact me or reply to my messages!!! Pathetic customer service.
