Huddle House review: Mobile order not prepared/no refund

Placed a mobile order to pickup at 2:20 a.m. on September 2, 2019. When we arrived to pick up the order, it was not only not ready, it was actually just viewed by the employee. She said the grease was burnt and she didn't have time to replace, so we asked for a refund since she already withdrew the amount of $18.58 from my bank card. She did not know how to give a refund either, she said that she had only been working there a few days and the cook was also a new employee. She told us to come back to speak to the manager later in the evening. When we went back there, there was still no manager on duty, and the employee said she couldn't do anything except write our number and name down for the manager to call us. We still have not received a call, and I haven't been refunded my money for food we did not receive! I am furious because this is not the first issue we have had with this location. I simply just need my money back.
