MIladys manager at longbeach is horrible with customers!!!!

I didn't expect bad customer service from a store manager. I am still in shock. I returned an item my wife bought byt first had to stand and wait until she was done on her phone chatting. Casually turns around and apologises. Then she asked my card I bought the item with and I asked why? With so much sarcasm in her face, she smurks and says because we must refund you. I told her I don't know your processes of this store so please explain. She explains but tries to embarrass me until I said "listen. If you come to my woek place, I have to explain to you how things work around there. So don't just assume or expect me to know how your processes work". She should be the example to her staff in the store, instead she is showing them different. I am ****ed off! I will encourage my wife to no shop there anymore and others.
