Good morning, I would like to log a complaint about our Pick n pay (service), their app and their customer service!Ordered shampoo & shower gel, it was not received, which I paid for. Invoice shows as delivered but items weren't received. I logged a refund via email multiple times! No response! Pick 'n pay's service is really bad!
