Domino’s Pizza complaint: Messed up order Terrible Customer Service

First: I was placing the order online. The page froze on the final page where it s. So I called the store to ask if my order came through. First they said Yes, then passed off to a manager who said that the order didn’t come through And then asked to make sure of this, he said yes, and that it will only be $10 because of a coupon (online the Pizza was $17) And that it would be 20 minutes (online it said 11 minutes).
When I arrived 25 minutes later, I was told the pizza wasn’t ready. After another 10 minutes I was asked to pay for the pizza, that I had yet to receive. I finally got a digital receipt of $17. I show the worker and he said I still owned, then I ask to speak with the manger (this is about 40 minutes after the pizza was ordered). The manager says the pizza has been done and just sitting there, I was handed a cold pizza. When I asked for the discount of $10 that I was offered, he said that wasn’t possible. I then asked why it was offered the discount and he said because I already paid for it I didn’t get it.
I walked out with the Pizza and right back in and asked for my money back. That is when the manager said that he couldn’t do that.
Here is when I got upset and demanded my money back, because the manager was being short and rude. He threatened to escort me out or call the police, which I replied That would be great, I love to tell them what is happening.
Here is where he refunded my money. After getting my money back he threw the pizza in the garbage and stormed off to the back of the store.
The only compensation I was offered was a 2 liter of soda. I left with no pizza and an hour of my life wasted.
Also, I was there long enough to witness an employee smoking outside, come in and go straight into making pizzas without washing his hands.
