Wrong order received twice

Worcester Brach had me drive out twice to fix an order they had wrong. When I got there , they wanted my slip that they took from me the first time I stopped there. When I told them that they took it and that I was there a few min ago they agued with me They changed the order and still gave me the wrong thing I am absolutely beyond upset with this This is not the first time this has happened They need to get their act together!!
