ICICI Bank — debit card fraudulent transaction

This is saurav tomar, account holder of icici.
I have been deducted for amount 7119.81 which i have no accountability
And knowledge.
This was the following test which i received :
"dear customer, purchase of inr 7, 119.81 has been made on debit card linked
To acct xx6082 on 24-nov-17. Info: vin*amazon uk p. The available balance
Is inr 90.32."

I have completed the task dictated by customer care executive, to file a dispute form in physical form with attached identity and debit card photocopy to the branch.

Case facts:

Such kind of transactions have happened to other customers also and there are various complaints on consumer forum which show ignorance of icici and state that those consumers are unsatisfied. (Photo evidence attached)
Particular to my case the transaction amounts to 7119.81 and is been to merchant amazon uk p which state it as amazon prime uk, since the transaction is done in uk region and user my involvement is null.

I hope that my case won't be mistreated and amount will be back to put my faith and loyalty back in icici banking institution.
Kindly look sharp through this matter.
Thank you
