Burger King complaint: Service

I used the Burger King drive through at this location. I presented 2 coupons for the family bundle and 10 pc. nuggets. I paid the lady at the window for my order and was handed my food. I asked if that was all of my order and the young man said yes. I pulled up and checked my order but it was missing the 10 pc. nuggets. I drove back around and told the young lady the 10 pc. nuggets were missing. She told me to pull up and they would bring it out to me. I waited 30 minutes and no order. So I ly got out of my car and went in. There was no customers inside and 7 workers. I told them I had been waiting for 30 minutes for nuggets. The lady at the window came to the counter and said yeah you had chicken fries. I said no, chicken nuggets. She said she would give my money back and an order of chicken nuggets. I told her I owed the money for the food and just wanted the nuggets. I expressed that this Burger King had the worst service ever. I always have to check my order to make sure it is right because this is not the first time I’ve had a bad experience here.
