Fedex — Invoice Documents Required for Custom Clearance

This is to inform that I have provided the required documents for value evidence but Fedex has not replied if they have forwarded the documents to the Delhi Customs or not and due to this the customs can charge me extra money for reactivation which has happened to me before due to Fedex's mistake of delaying the procedure.
Please check and reply as i have given all the documents before hand and will not levy extra charges due to delay.
There has been no reply of my mails and no phone calls were answered for the same issue.
Please check and get back to me.
