State Bank Of India [SBI] — state bank of india [sbi] credit card 7835- unwanted sms receive

Dear Sir/ Mam,
I've got an SMS regarding legal notice against outstanding of Rs.59, 934.73 on credit card ending 7835 and ask me to pay dues immediately or contact Abhinandan Singh at [protected].

I called on that mention number to Abhinandan Singh. I talked to him regarding the received SMS. He said that "you have a credit card, which starts at 2 months before and you have used it up to Rs59, 934 and pay it as soon as possible."
The problem is I have only one credit card of SBI with the credit limit of Rs 60, 000/-. Which is 1year old.
That person has my personal information like my address, my contact information. I don't know how he got that information. I am afraid that he has my account information.
I don't know what to do next.
