Sonic Drive-In

I was charged what seems as if two different meals. I was charged $16.32 for the meal I ordered. But I was also charged $4.74 and I don't know why. I didn't realize I was charged this additional charge until I got home and checked my bank account. This happened on Sunday November 24, 2019. My number is [protected]. I would like a refund for the $4.74. I don't know what else needs to be accounted for in this paragraph.
