Zestmoney — NOC of my loan

Address:

Site No. 19 & 20, Indiqube Celestia, Ground & Third Floor, Koramangala 1A Block, Koramangala, Bengaluru, Karnataka 560034

I took a study loan (Loan Id- 41A4017F7442) from Zest Money in the year 2020 and repaid the complete amount at the end of 2020. The loan is still showing active and due to this, I am not getting any other loans. I have been following up since 2021 but neither their support number ([protected]) is active nor they are responding over emails.
I need the NOC of my loan and the same to be marked as completed on all the necessary portals.
