How do I complain about an online store in the UAE that never delivered my order?

Paid in full, nothing delivered, and a seller gone silent is a straightforward consumer complaint — and you should also move on your money through the bank in parallel. First, the complaint: if the store is licensed in Dubai, file with the consumer protection section of the Department of Economy and Tourism; for stores licensed elsewhere in the UAE, the Ministry of Economy's consumer channels or the relevant emirate's economic department handle it. Attach the order confirmation, payment proof, the delivery promise, your chasing messages and the dead tracking number. The authority contacts the trader, and licensed businesses tend to respond quickly once a regulator is involved, because their licence is at stake. Second — and do not wait on the first — if you paid by card, ask your bank to raise a chargeback for non-delivery. Chargebacks are time-limited from the transaction date, and two months have already passed, so start that today. It is also worth verifying the store's trade licence; if it turns out to be unlicensed, report it, though recovery then becomes harder. If the amount is significant and both routes stall, a lawyer can pursue the company directly through the courts.
