McDonald's dropping the ball

McDonald's in Elis Park got the my order wrong after i mentioned it was wrong they then took more than 20mins to do a breakfast wrap with fries. And lastly they made me feel and look like I was in the wrong for mentioning they were wrong, I am not impressed with your service and I will be telling all my friends about this. PS the was only 3 customers in the store and 2 cars in the drive thru
