Poor service from Pick&Pay

We purchased ribs Sunday from Delmas P&P.The ribs were off and the smell was sickening. We wrapped the ribs in plastic and left in the cooler box to return to Delmas after the family left for lunch. We arrived at Delmas only to find that they closed, this was at 5:30. We hoped that they might still be open most P&P close at 7 on Sunday. We decided to go to Springs P&P and ask for assistance. We could not leave the ribs as the smell was so revolting! at Springs, a lady assisted us, we explained the problem to her, A long explanation was given, all P&P have different owners, and can't be held liable.The owner of Springs branch stepped in, the problem was also explained. We asked for assistance from him, as we did not want to take the ribs back home because of the smell. He walked away with out greeting or apologising for not assisting. We are reasonable people there is a way you treat clients the manor that he did this, was unacceptable. Delmas for having off meat and Springs for there dreadful service. I would rather pay double at Woolies. P&p is willing to swipe a smart shopper card at branch? if I buy a shirt at Edgars in Sandton am I not allowed to return it to Boksburg??
