What to do to reach a settlement for credit card debt with the bank

Good day Sir,

I have a credit card due of AED 6000. I left the UAE in 2019 but now I have to pay my total outstanding due which is AED 6380.

So I tried to mail the bank but I don't get any proper answer that they can give me any bank account that I can pay my dues or any settlement.

Now I am confused about what to do. Please guide me on this. I wanna clear this due. I got a travel ban also. I want to remove this burden from my shoulder.
