Sonic Drive-In complaint: A Sad Day at Sonic

I got a text message from Sonic advertising a small classic milkshake for 1.99 good thru 6/12/23. Stopped on way home, arriving at 10:45 pm. Went onyy to o app to order but no coupon code xss as me up for discount. Went back to my t text message and clicked on link for that promo. As gain no way to get discount offered so pushed carhop button for help. They said I had to order from app. I said the app didn’t offer discount code, response was they must not be on sale. I said I had a text message and I had seen or heard an ad about it earlier that day. Sorry, nothing they could do. I asked if a person could come help me bring up the code, they were not happy about my request but did eventually send a person out. By this time, it was after 11:00 pm which was less than an hour from closing so no app orders allowed. This person fave me the run around, making every excuse she could come up with to not honor that price. She said ca HD e would go in and see if she could find a promo code and would let me know. It was almost 11:30 and no response so I pushed button to see if anybody was still there. They answered and said they couldn’t find a as code so they had called a district? Manager to see if they could do anything and they had not heard back from anyone yet. I went online and found a link to order through, but be a ugg as it was Al
OST closing time, my order didn’t send through. I told the staff that and they said it had to go through apo. I told them it said if you are at restaurant, just tell them you want the special and they could do it without an app. I did, they just flat refused to help so I drove off as they were closing. I feel I should receive some free food for my 1 1/4 hours sitting at their place with no help!
