Kind people of GV, can you please let me know how and when to use a credit card my family has recently taken sbi super save to gain points and rewards.

Don't just pay the minimum amount . Try paying the full amount .

Would appreciate if somebody could let me know the basic pointers when using credit cards, ik you aints supposed to withdraw cash with it as high interest

Pay in Full and Pay on Time

Swipe a credit card only if you can pay that with your debit card. Credit cards are not free money, it's like you are borrowing from your future self. Eg you like headphones on amazon worth 5000/-. Swipe a credit card only if you can buy that with your debit card. Also, always pay in full, no matter what.
