Marshalls review: Charged twice for one item at Marshalls

H,
My Bill number [protected], date 07/24/2021 time 15:20:20
I purchased 10 items but I got billed for 11 items and got over charged by $6.99.
One item with same code is present on my bill and I got only one item for that code.
This is very disheartening experience I had in Marshalls today.
Can you please tell me the process to get refund or store credits.

Store location:
Marshalls of Stevens creek, 5160 Stevens creek BLVD San Jose CA 95129 US, [protected]
