How to claim back amounts paid to a supplier in Dubai for goods they never delivered?

My name is N. from [-------- Ltd], an importer of energy storage products based in New Zealand.

We are in the process of seeking a refund from our supplier (an LLC in Dubai) to recuperate funds from deposits we have paid for stock that we have never received.

The total credit we have with the LLC is USD $68,030.62. This is split across 2 orders; the first purchase order is dated 4th March 2021, and payment was made on 9 March 2021, totaling USD $29,217.50.

We then issued a second purchase order dated 26th May 2021, and payment was made on 3 June 2021, totaling USD$38,473.12.

Total payments and credit on 3rd June 2021 were USD $68,450.62. The total goods received on 3 June 2021 were USD $420.00. Total owed to [------Ltd] on 3 June 2021was $68,030.62.

This was delayed until November 2022 and is still not ready, we issued a formal order for cancellation on 14 December 2022.
