They delivered what I didn't order

KFC Northriding inconjuction with Uber Eats.....I am not happy at all....on my order I had bought 1.5L coke but when the delivery came they brought 2 buddies which I had told them that I do not want and I am going to cancel the order....to my surprise the delivery guy brought them anywhere......KFC staff said it's not in their power to do anything abt it...if I want to do anything I should deal with Uber eats
