Zestmoney — EMI Paid but it still shows overdue/ harassment by loan agents

I have an ongoing lon from zest money whose payment was auto debited by NACH on 5/7/21. The payment has not been updated and as a result the emi shows overdue. I get 5-6 calls a day from zest money agents from unknown numbers and my CIBIL score is at risk.
I have already called thrice, emailed Zest 4 times and posted on their twitter so that they recitify it but haven't recieved any updates. I am still getting harrassed.
The company needs to update my payment - it has already been 10 saya since I paid it.
