Hi, my parcel tracking no. RC781391135SG has been held by customs. My local (Singapore) postal company said that reason is due to missing invoice of the item. They require the recipient to send them the invoice, but the recipient is a large corporation and seems unwilling to help me respond to customs, and instead sent me the e-invoice for me to forward it to China customs. However, I'm unable to contact China customs, is there any email I can send the invoice to so that they can help me forward my e-invoice to the customs for the release of my parcel? Pleaseee and thank you!

Packing reference : EW16496157FR
You indicated that the package was blocked due to the lack of an invoice.
However, the invoice is in the "DOCUMENTS CI-INCLUS" pouch attached to the package.
Please confirm the problem is now resolved and the package will be delived fastly.
