Utterly disappointed

My first experience with Pick 'n Pay online shopping and I am absolutely appalled at the experience. Every retailer knows that Black Friday is the biggest shopping day of the year and they should plan for it accordingly, except for Pick 'n Pay. Almost every item that they advertised online was out of stock or was "not sold in my area" no matter what area I choose. I have logged a call with the call centre after finally get a hold of them after 3 days of waiting 30 hours each time, to advise that I did not receive my order for 3 x Douwe Egberts coffee. Mzuzo was meant to call me back in 24 hours after getting a hold of the store to confirm stock, he never got back to me, I had to call again after a week to follow up. He left 2 messages for me saying he was still trying to get a hold of the store. Another week has passed, and I still have had no response...Seriously how difficult is it for a store to confirm stock???? The call centre is a nightmare to call, you can never get through, and when you finally get through the service is so poor.
