Negotiating with banks in respect of outstanding dues

Hello.

I owe a bank here in the UAE a credit card debt amount.

Due to circumstances (losing my main source of income, having other financial burdens, including monthly medical bills for cancer treatment & medications etc., and  I don't have health insurance), I haven't been able to pay back on time since over a year ago.

Hence, that amount has since accumulated from a small figure to a relatively big one (currently at around AED 70,000).

I have received an email recently from some "credit collection" agency, saying that if I don't pay back next month, they'll put a travel ban on me and file a civil case. However, it is impossible for me to pay this amount at this time.

I am currently making "some" income (not as close as I used to before, but still), and have the intention to resolve this issue.

Is there any way to reach a settlement with the bank (maybe to waive part of the amount or the interest), break down the monthly installments to smaller amounts, or any other solution you would suggest?

Many thanks.
