Kotak Mahindra Bank — I have received 180 call in one day from personal loan department

I took a personal loan from Kotak bank in 2019 and I am almost regularly paying EMI and last couple of months I have been delayed but paid end of the month with a late payment fee and bounce fees. last month they recovered EMI through UPI pay and also submitted ECS. so this month I have said 1 Sept you again submit ECS so I refused to pay through UPI.

but I receive every day starting 10 calls a day and yesterday(31st Aug 2022) it reached 180 calls in one day.

after a delay in payment, I am paying the required frees but still, these many calls are not acceptable
below are numbers from i have received several calls a day
