Bad Service

I which I could give a zero rating for DHL they have no idea what is customer services. Customs has my parcel and I needed to provide documentation for the release. I got their email requesting the documents I sent them 8 minutes later the documents. That was on the 17th of November I followed up on the 20th asking if the documents was correct but did not get a response on my email so I phoned them asking that they sent me the status i.e. was the sufficient documents. It now the 24th I have been sent around the block not getting any feed back. Now they let me I need to sent an email. I have done that and got no response. Spend a 30 hour on the Phone not feed back
