Review: Very bad return service. - ​I am writing to express my severe disappointment regarding a product. ​The item, which is a pair of earbuds, was clearly not properly packaged when it arrived. Furthermore, the seal appeared old or tampered with. ​More critically, the earbuds are completely non-functional and do not turn on. I have been sent a defective and faulty product. I did not expect this level of poor quality from desertcart. ​Given this experience, I no longer wish to keep the product. I request a full refund immediately. Please arrange for the return of this defective item and process the refund to my original payment method. ​Sending out faulty goods is frankly insulting to the customer. Please treat this matter with the urgency it deserves.
