Poor customer service, first need a till-slip

Hi, I need to make the customer aware of Dairy ****s policies and procedures: If you have a complaint about their products, you need to produce a TILLSLIP otherwise they will not assist you, management orders! I phoned them again today but were told that they can't help if I don't have a till-slip. I was still speaking to Rugiane, and he just disappeared, very unhelpful. Then I spoke to Tibani and she said she will escalate the matter to management... They wanted a receipt to prove I purchased the ice-cream... REALLY? who keeps a till slip from SPAR for items bought cash? they said it will take 14 days to investigate. I have sent pictures of the ice-cream to their WhatsApp number ***), NO RESPONSE! The fact is obvious, they do not care about the consumer nor have they any intension to rectify. Shame to you Dairy-not-made..
