Online pick n pay worst ever in online shopping

Pick n pay is the worst when it comes to online shopping. They advertise good which they don't have in stock. They than let you pay for your order and than cancel it due to no stock. Than you have to wait more than a month for your refund after you have to fight with them for the refund. I will not recommend anyone to shop online with them. No customer service you have to wait 20minutes plus before someone attend to your call
