Action Fraud are a waste of space they never seem to care when we report thing. Unless its the Government being defrauded you will get no where with them.
I have been ensured this has been passed on to the DHL IT Security by a contact.
The owner of the PC that sent the email may not be in the UK
The person running the bot net is not going to be in the UK
The owner of the fake website will not be in the UK
The registrar of the domain name will not be in the UK
until the top level domain hosts more tightly control registration of domains and make it easier to shut down scam sites this is NEVER going to be fixed
