*****ulent sale

Tops at Spar the one in Vredehoek Cape town Yesterday I ordered a carry pack of savanna 500ml and received 330ml on Uber eats when I asked the driver he said I should take it up with Spar because he is just a driver and didn't pack it..when I called spar they gave me a runaround saying it's ubers fault and they don't want to take accountability for this. At the end of the day I payed for a 500 ml but didn't receive which means I lost my money ...I don't appreciate the manner in which this was handled as I have been waiting for a call from them since yesterda.I want this matter handled ASAP as well as my refund
