Tracking my parcel EL020298376RU I,ve seen that it should be declared by the recipient to the customs. There wasn't any calls or messages for recipient although his phone number is on the documents. All receipts are inside the parcel. All documents were sent. Can he send copies of documents by e-mail? And where should he send it? Get you give contacts or address?

How can I provide documents / invoices for customs? I am returning a product purchased through the online store.

Current status:
My shipment/documents have been in transit for 21 days.
I would like to know where my documents are currently located.
Reason for delay:
Why has the shipment been delayed for such a long time?
Is it stuck at customs, sorting center, or in transit between countries?
Expected delivery time:
When can I expect my documents to reach the destination?
Confirmation:
Can you confirm that all necessary steps have been completed from your side (e.g., dispatch, customs, handling)?
