What's happening to Pick n Pay???

Yesterday, Saturday, 30/08/2024, I went to Pick n Pay, Main Road, Wynberg, Cape Town, liquor store & I bought a Castle Lite 750ml beer, & earlier today I went back to said store for a deposit refund for the empty bottle, only to told that I had to buy something else, "we don't give money for empties", what utter bull**** is this, there is no signage to this effect stating that, it's not about the money, but about the principle, Pick n Pay, what is going on?, it seems like your staff are doing us a favour by serving us...,how do I give Pick n Pay, less than zero stars?, you definitely don't deserve any stars, let alone 1 star...
