Sonic Drive-In

This is the second time I have to this store and my order was messed up. They forgot one of my drinks last time and they gave a chip for a drink that I used this visit but mind you they didn't apply the discount and then they forgot one of my slushes again? And on top of that my drink was super messy and sticky . I'm not happy with the service I have been receiving at this location . I'm tired of complaining to the store🥺😡
