Don’t order anything from this store on the mobile app. I ordered two drinks Tuesday night paid and headed to the store. When I got there the app was not allowing me to check in do to technical difficulties with the app. So I headed to the door to speak with a staff member. Told them the issue and was told I didn’t order anything and that if I didn’t leave the cops would be called. I stated that was fine and that I would wait. She then stated she is the manager and would not be helping me then walked to the back of the store. The other lady’s who were on the line just stood there. So I got in my car and went to the drive thru to see if I could get a phone number or something to call because it is your app that did not work not my fault. This is unacceptable you are taking peoples hard earned money and not providing them with the items purchased. Called customer service just to be told it’s not there problem. You all should be ashamed of yourself. I WANT MY MONEY BACK!!!!

If you care about your health, families health or well-being DON'T EAT OR DRINK ANYTHING FROM HERE!! They knowingly serve dayyyyys re heated OLD DISGUSTING food, Management is HATEFUL, THREATENS TO CALL THE COPS over simple complaints is extremely Hostile and ignorant. I honestly have never seen anything like it and I dont know how the health department or someone hasn't shut this place down. I was put in contact with the "High priority" team via the franchise owner info but I highly doubt anything will be done. Even though we became very ill from these old, re cooked corn dogs and still arent feeling well a day later. Please, STAY AWAY FROM HERE!!
