Loan settlement with the bank in the UAE to stop harassment by collection agency

Hi

I am from India and I left the UAE in 2020 with a personal loan outstanding of 300k due to my job issues, I am in the UK currently for the past 2 years.

The bank has received my end-of-service benefits and holds them. Now they are threatening me via a collection agency from India to go against my parents who have nothing to do with this loan.

They are calling them by phone and messaging to threaten me from time to time. I have complained to my bank about this bullying from this collection agency but no action is taken from the bank.

I am currently paying the minimum amount to the bank in the UAE towards my personal loan.

I like to know what action can the UAE bank take against me in the UK and in India against me and my parents.

What is the legal right the collection agency in India has to act against me and my parents?

If I can't pay my personal loan due to my financial situation, what will the consequences be?

Kindly advise.
