After query by Mr.karstik sure on phone, no new credit card was issued to me for discount of 25%. Hence recovery of Rs 7505 is deducted from my Credit Card. He told meand assured that the amount will be adjusted through reward points and the same amount will be credited to my account(with in 48 hours) before generating my bill. The amount deducted in epaykerela, The transaction is yet to be claimed by the merchant.
In view of such type of incident, I request to kindly arrange for return of amount debited from my account Rs.7505.00. So that the faith between a Customer and Bank can be restored and maintained. I am hopeful for yours kind co-operation.
