Terrible Attitube from a Manager

I have sent the message below to the Chicken Licken Customer Complaints on the 16th April and did not get response since. "To whom it may concern: On the 15th April 2016, i visited a chicken licken store in my neighborhood (Queensburgh). I had my family over and we decided on buying chicken licken. I arrived at the store approximately 18:45. In front of was a gentleman with two children. This gentleman had some issue with Lee Ann( which i didn't know was the manager at that time) about his food getting cold. I didn't bother about that and proceeded to the till when i was called. The cashier took my order which was a hot wings meal 8, full house family meal 8 piece and 2 x party sixteens. When the order was called out, we realized the 2 x party sixteen was not in the order and it was family meal 6 instead of 8. I checked the slip and noticed it was not ordered. I then said to Lee Ann that the 2 x party sixteens were not ordered and if she can please put that order through. She asked me to pay first. I decided to leave that meal out because the line was too long to wait to pay and there was just one till open. There was a family deciding on what to order so i asked her if she can please swipe my card for the meal as we know what we want whilst that family decides. She rudely and arrogantly asked me to wait my turn. I said to my brother let's leave because these people are useless. And then Lee Ann starts shouting at me. I asked for the manager and she said she was the manager. I asked her is this how she speaks? I said to her that the customer is always right and she abruptly said what if the customer is wrong? I said to her I'm going to complain and she shouted saying " there's the number there, go complain". Besides being humiliated, i was so embarrassed. She embarrassed me in front of my family and the customers in the store Is this how "manager" should speak to customers? I have been supporting the Queensburgh store from the day their doors opened. I am a branch manager for a big company and always treat my clients with respect. I always support that store especially treating my clients to chicken licken. This is not the first time is experienced a problem with the store but never complained before. I would like to know how this matter is going to be solved and what actions are going to be taken towards Lee Ann. I personally think Lee Ann has a disgusting attitude. My order number is #2071 If i am not contacted i will take this matter further."
