Pizza Hut

First time ever trying to place an order Online with a coupon June 8, 2015. I called the nearest where I wanted to place the order and the employee asked what kind of coupon was it. I said a Pizza Hut Coupon that is Online. She said she had nothing to do with the coupons Online. I replied "this is what I want." She said You gon get that sensitive over a coupon you god damn b**** and hung up. I went to the restaurant and addressed her by her name as it appeared on the back if her shirt.I said________, I am the one that you called a b****. I asked for the manager and the district manager's name and she gave me her manager's name and a phone number. She said "Do you have the coupon?" I said no! She replied "Is there any other reason why you should be in the store and she walked away from the counter and walked towards the back of the restaurant. I called the phone number that she had given me before leaving the restaurant but to no avail. I went to my car and called he number again at this time she came near the entrance door of the restaurant removed the we floor sign. I sat patiently in my car until I was able to reach the restaurant manager.
