Today I received a SMS stating that - Dear Customer your BOB ATM card today has been blocked ,Thank You for Registering with ICash DMR Services .Please use this Verification Code (177196) to Activate Your Account

The caller was asking me to update KYC on profile. My KYC is already done long back.

I called back the caller after sometime and asked him from which location he is calling. I have a serious doubt in my mind that this is some fraud.

Please advise
