Sonic Drive-In

We went through the drive through in grove city ordered 2 dbl cheese burgers with bacon. Our cheese burgers had no bacon the buns were rock hard! We were charged for dbl bacon cheeseburgers! We also have a $10 gift card that we can never use. They say it won’t work. I’ve called the number on the gift card and it has $10 on it but yet we cannot redeem.
