Submitted request to consolidate 4 packages on 12 Dec 2023. After more than 1 week nothing done, contacted them only gave excuse due to overload so delay. Days later, inform one of the package was missing. Requested to consolidate the remaining 3 and ship out, the other regard as missing and do a refund to me. Leyifan insisted they wanted to find the missing package in the warehouse and again after few days still missing. Now i have 1 package missing and the other 3 after more than 2 weeks still with them. There is no sense of urgency in helping customer to resolve the issue. Work ethnic unacceptable, unreasonable, irresponsible and unprofessional.
