International Debt Recovery IDRWW

[Guest]

Received a letter and 2 emails regarding an old credit card balance left in Dubai. I paid off the majority of the balance after returning to the UK but lost my job and didn't pay the final installment. IDR are now stating i owe the full original balance so none of the 4k i paid has been taken into consideration. Their email says they work as agents for Emirates NBD. Has anyone had any experience with this? I am tempted to ignore but not sure how much power they have and what the consequences are. i have emailed emirates NBD asking what my balance is as i am willing to now pay them the balance but not willing to pay what i've already paid back. ANY advice or experiences would be greatly appreciated its worrying me i am now being chased for debts i worked extremely hard to pay off.
