State Bank Of India [SBI] — credit card collection extremely rude calls to non referred friends and relatives

Hi,

Myself saifi Gulati...used Sbi credit card long ago whose payment is supposed to be done...I m not using my mobile number which was in the documents at the time of issuance of card...moreover not in town as well as not in correct financial position to pay all dues...

My friend and relatives are receiving rude calls from this number ([protected]) some collection agency of SBI and making remarks such as Paisa kha gay and all...and fake information like I have given their reference in the documents...

People are messaging me on social media that we are receiving such disgusting calls...seeing this I have called on this number and tried to speak with the lady that why are u calling on these num when u have one of my extra number...then she is saying i[censored] will not be available, then we will make such calls..

I want to know where it is mentioned in the collection norms that bank have all rights to make rude calls to friends and relatives in case customer is not available...

The card is issued on the name of saifi Gulati...

Please respond to me asap
