No Truecaller. I disabled spam protection. (Even if spam protection, my phone let me know who called at what time. It's just that it won't ring or inform me, but I can check those calls in call history.) There is no such calls.
I have noticed such things mostly from sbi card in recent times. I have informed the same to nodal officer and asked to initiate an internal investigation on this matter.
