State Bank Of India [SBI] — Double deduction for same transaction

Address: New Delhi, Delhi, 110009

Sir/ Madam
I purchased goods from a store on 20 June 2017 using my debit card, and am surprised to find that there has been two deductions for the same transaction. The store provided me the details of the transactions where it showed that there was only one time successful transaction from my account for the said items. I have complained about it to SBI and received the complaint no [protected]. But I still haven't received any update on this matter.
Kindly look into the matter at the earliest.
Thank you.
