Temu Suitcase Arrived Damaged and Return Option Does Not Work

I ordered a Suitcare suitcase from Temu and received it on 28 July in Dubai. The suitcase I received is of very poor quality and arrived damaged, especially around the zipper area where the surface is already worn and scratched. For this product I paid a total of 374.46 AED. Temu only offers Redbox as a return option, but the suitcase is 34 inches and far too large to fit into a locker, so I cannot practically use this method to return it. Since 28 July I have been constantly writing with Temu customer service to find an alternative solution or to receive a refund, but for almost two days now I am only being put off and no real progress or concrete solution has been offered. I request either an alternative, workable return provider instead of Redbox due to the size of the suitcase, or a full refund of the amount I paid. I ask for this issue to be resolved quickly, as the product was delivered damaged and unusable for me and the current return option is not suitable in my situation.
