[Resolved]  Idea Cellular — south indian bank sbi credit card fraudulent transaction to idea cell-billdesk

Address:

Ernakulam, Kerala, 682508

Yesterday evening (15-Feb-2018 6:32pm) I received a call from an unknown number([protected]). She told me that she is calling from SBI Credit Card Office and has called regarding bonus point claiming matter.
She stated that I was having bonus points for all the transactions I've made till date and I've not claimed it yet. Also added that this bonus points have been expired and she will recover this expired points for me, and for the same she had asked my card details. She told that I'll get an SMS about the payment credit after the call. But just after the call I was shocked to see the SMS. Instead of credit, a debit have been occured from my account. The message I received was,

"Rs.4, 876.00 was spent on your South Indian Bank SBI Card no. ending XX2281 at IDEA CELL-BILLDESK on 15 Feb 18. Remaining credit limit: Rs.4, 107.50."

I immediately called back in that number, but it was told that, "the number you are calling is not available".

I've lost Rs4876/-. The amount is transfered to IDEA CELL-BILLDESK. Please do the needful to refund the amount from them as early as possible
