In 2023 , for the Bill of July month, I paid full bill of SBI card on 3rd August, credited on same day in the card account, the due date was 7th August. SBI card reported delayed payment by 3 days, my CIBIL score dropped by 31 points. I complained. They first denied all this. When I escalated upto Customer Service Head level, they removed the entry. But, to my surprise, all previous payments done by me for SBI card since last 4 years got vanished. My scores improved by 12 points immediately in the the next month. But for the recovery of lost score, It took 8-10 months.
There was not any fault from side, still I suffered.
