KFC India — Incorrect Deduction from Credit Card - POS Machine

I visited your Mumbai store, which is located at the Level 3, Terminal 2 International airport Mumbai.
My Order id is : MK[protected]
POS No is : MK0111
Inventory No : [protected]
Token Number : 3821
Bill Amount : 790
Date :[protected]
Transaction time : 15:19

Your staff has deducted 7900 rs instead of 790 rs on my credit card. Kindly help me sort this issue out and how can i get my refund at the earliest.
