Trendon Epay Kerala — fraud transaction

Sir,

I got a call from [protected] telling me that reward points on my sbi card is expiring and that these will be enchased to my card.

I was asked to share my card no, and cvv. I refused the same. To prove authenticity they shared my entire billing history, last transaction details and payments made.

On sharing my card details, immediately a transaction of rs. 7840 was made on my card by trendon_epaykerala.

I called sbi helpline and got the card blocked but was told that the transaction is already done (Under settlement), i would like to get this transaction blocked.

Kindly help.

Regards,
Mukesh tiwari
