SBI credit card

Hey all. I had applied for an SBI credit card at a mall where these SBI executives hound you about getting one. Benefits seemed okay so I applied. I didn’t hear back for a few weeks. Now they keep calling me asking for the same details that I had already provided, like PAN, mothers name, address etc. I’m skeptical to provide these details over phone as I don’t know if they are scammers or actually people from SBI. They keep saying that they are from the dispatch department and just need these details to send the card over in 2 days. How do I verify that I’m not getting scammed and that they are from SBI?
