Bad service from Tiger Brand

I phoned Tiger Brand Monday morning 8 of Feb. As the instant porridge that I bought, I found worms in it. The operator taken all my details and asked me to send photos via whatsapp as I did immediately. Today is Friday. The whatsapp message was delivered but up until this time was not read. I phoned everyday and the operator could not give any feedback. Why do you then add on packing your customer care number if problems cant be solved. Also people please check the instant porridge for worms.
