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!

Dear Sir/Madam,

I am contacting you regarding my parcel number EW164572295FR, which is currently being held at customs in China due to a missing invoice.
I would like to point out that I was not contacted to provide this document. However, I do have the invoice and I can send it to you immediately in order to resolve the issue and allow the delivery of my parcel.
Could you please let me know the correct address or method to send you the invoice?
Thank you in advance for your assistance. I remain at your disposal for any further information.
Kind regards,
