Spoilt pick n pay brand long life milk

I bought the pick n pay brand long life milk, which spoiled. I contacted Brandon Winnaar from customer care. I didn't have a receipt as I purchased the milk a long while back, it was still well before the expiration date, it couldn't be picked up on my my smart shopper card, and Brandon left it as that without reply, because there was no receipt or electronic trace. I bought this at the chatsworth branch. Now I can't buy the pick nd pay brand at woolworths or spar, it can only be purchased at pick n pay, if they think I picked up the box in the bin somewhere and looking for false reimbur*****t, really I don't have time for that. Other brands have compensation without receipt, as long as I had pictures of the product and what when wrong with it. I would advise others not to buy the pick n pay brand, because you are not protected if you don't have a receipt or they can't trace it on the smart shopper card. There are cheaper, quality brands who give excellent customer service
