RBL Bank — credit card used from rbl bank registered number ([protected])

Address:

605003

My credit card is newly activated by this month 03.01.2019 and is being used by me via online and card swiping method. I have received message stating that "as per your request, r-shield insurance program has been activated" on next few days. I have sent a mail regarding the same to rbl consumer compliant mail ids on 09.01.2019. Even though, they have sent mail on 10.01.2019 stating that "r shield program" is activated and product price is rs.15000/-.. Without my knowledge they have activated the insurance program.. I have conveyed the same.. But there was no action taken from their side. Now, rs.15000/- has been added into my account and need to pay the same. Please consider this complaint sympathetically and do the needful, as i haven't given my consent to activated this insurance also rs.600/- deducted for activated theft program. Kindly revert the total rs.15600/- immediately... I am sure about i didn't give my consent to activate the said programs.
Later, I have received a call from RBL Bank credit card team (from [protected] & [protected]) on Saturday 19.01.2019 (03:00 pm) and told that our complaint has been forwarded to them and they are there for resolving the same.
They have verified our details and asked credit cared details, valid till... Later he asked CVV number which i haven't given to him.. Since, i had doubt about them, i didn't give CVV...
He insisted to get CVV number.. He told that if i give CVV, then only he can able to to revert the money Rs.15600/-
What kind of habit is this? RBI and other banks are not recommending to give CVV, OTP and pin.. But a person from RBL Credit card called and asked CVV.
Then, I have received a mail from [protected]@india.com – REFUND TEAM on 19.01.2019 stating that “As per your mail we are forwarding your issue to RBL Bank and they will call you and provide you better resolution. If you received call from RBL toll free no ([protected]) then you do the process you have valid proof that you received the call from toll free no.
Today, I have received a call from RBL registered complaint number ([protected]) and asked CVV which I have gave to them because it has came from RBL registered number. Later they asked Verification code which was sent to me by them. After a minute, I have received main and message that I have swiped my card for Rs.15999/- twice.
I don’t know what is going on? from RBL registered complaint number ([protected]), I have received call and they debited Rs.31998/- today (25.01.2019 at 10:49 am)…
Totally I lose Rs.47598/- because of RBL Bank.. Kindly do the needful at the earliest.
