no feedback and delivery

This has been my second hellopeter complaint about Dhl in last 2 weeks. Bad service. I have been phoning for the past 3days to get sent my customs invoice for my parcel to be delivered and everytime I get told we will sent it. I keep getting smses to pay the invoice before they can deliver.but no invoice has been emailed. I have confirmed my email address twice. Please can someone at head office sort this out. I am paying for an overnight express service and not a snail service. My email to Clarify again is [Email Removed] *** tracking nr.
