sbi cards state bank of india credit cards SBI Cards Gundas came to my house, abused me and threated my mother? What should I do? wazirpur delhi

I took sbi cards 2 years before and missed payment last month. On september 12th 2023, gundas came to my house and abused me infront of my wife. My mother is running a stationary shop nearby my house. gundas told that if payment is not done within night, she will not be allowed to run her shop. Then they went directly to her shop and threated her. SBI Credit card was only in my name and my mother not even knew about it neither has she signed any papers to sbi. On 13th september 2023, threatening calls came to my mothers mobile number from 0484-4245644 and 9746628742. My mother , out of fear immedietely paid the money without informing me from her pocket.  I am planning to complain at local police and also move to the court for the abuse done by outsourced sbi cards gundas at my home. Apart from this , how can i get justice? Most important thing which depressed me is they threatened my mother going to her shop while she was no where involved in this.
