Online shopping stole R390 from me!

<p>I ordered nappies that were on special on the website. When my order confirmation came through they were about R100 more than the special, as the delivery date was after the special expired. When the store phoned me - I asked them to find out whether they could give me the nappies at that price, as the only reason I'd ordered online was to get the nappies special. No one got back to me. When I got to my parents' house after work and picked up my online shopping delivery, the nappies were not there. However I was still charged R390 for the nappies. When I emailed PnP, they said because my parents had not indicated that they were missing on the delivery slip, they won't refund me. The store obviously know they didn't deliver them though.</p>
