Negotiation for the restructure of a loan with bank

I have a personal loan at Dubai Islamic Bank. I was paying regularly but in 2016 me and my wife were having financial difficulties so I skipped 2 payments.

I kept paying regularly after that and wasn't able to catch up on that missed payment, and when my company was about to renew my visa, there was a case filed against me by the bank, so I got jailed.

To to cut it short, I paid an amount that was placed on what I am assuming the security check.

But until now they are still calling me and asking me to pay the remaining amount of my loan and threatening that they will file up another security check to got me jailed again.

I am very concerned and stressed as I am traveling by December of this year.

Kindly help please.

Thanks.
