HDFC Bank — Jumbo Loan

I am Sandesh having SB Account in your HDFC bank old airport road branch, bangalore had taken jumbo Loan of Rs 3, 00, 000 in the month of December 2019 ( st week) with the monthly EMi of RS 7327.34.
I had paid EMI till date without any delay. I have arranged funds to close this Jumbo Loan in the month of march 2020, I tried calling customer care nearly 10+ times in the last week of March and beginning of April, however due to COVID-19 I was not able to get customer care support to close the Loan.
I had paid Rs 2, 60, 000 from my HDFC SB Account to Jumbo Loan Card number ends with 4210 via net banking.
After April 1st week I made several attempts to call customer care number of HDFC to close the pending loan Amount. I have visited HDFC Bank karthik nagar branch bangalore, however i have not received support from Loan department.
I have called HDFC personal banker ( Nabeela) nearly 10-20 times from April- June 2020, however it was not connecting to Nabeela. I keep on getting due to COVID-19 message. Only 2-3 times received the call.

The final amount after the pre-closer charge she told me in the month of May and June are totally different and not matching at all. Looks no seriousness in telling one clear final amount. I have audio recordings of conversation.

I have raised this issue on the HDFC website under the query section on 16th May. However till now no one replied. Only auto forward message from [protected]@hdfcbank.com

I am annoyed with HDFC bank support with regard to jumbo loans. Unnecessarily Interest from April to till July is added. Tell me who is going to pay that????
Again from June new personal banker Sandhya is assigned and she called me in the month of June 1st week, After from June till today (4th july 2020) i have been calling[protected], She calls back later in the day and told that she is working from home and someone from office will call back. So far no one called me. Again delay from HDFC bank.
With these it clearly shows delay from HDFC bank side and I dont want to pay any additional interest you are charging from April till July.

Please help me to close my Insta Jumbo Loan as soon as possible with reduced interest
