KFC India — kfc kolkata - gariahat money deducted but order was cancelled

Hi, my name is abhishek and i have visited kfc store which is located at hindustan park, golpark, gariahat, kolkata on 30-aug-2019 at around 03:20 pm. I ordered burger, chicken popcorn and 2 drinks and the bill was rs. 175.99. I have given my sbi debit card and the attendant tried but she said the transaction was failed due to some network problem. And then i paid the order in cash. But when i returned to home i found that rs.175.99 was deducted from my account for my order which i already paid in cash. I returned to them to enquire and they said the money will be refunded in 4-7 working days. But till today (After 8 days) my money was not refunded. Please find the transaction details below from my email. Thank you for using your sbi debit card 524xx0866 for a purchase worth rs175.99 on pos kfc, at kfc, txn# 214934. Please refund my amount asap.
