DHL has terrible customer service. You can't get anywhere on the automated system. I finally just got transferred to the billing department even though I didn't have a billing issue, just to talk to a live person. Our package got returned to sender even though we emailed to requested documents before the dead line on the email received. So we tried to send it again. Now it has happened again. Now it's a 24 hour deadline. There is NO automatic email response letting you know that your email with requested documents has been received. So, when you try to call DHL to see if documents have been received. I was told that they will email you back once received. That was NO HELP. :( WELL... lets hope it's before THEIR 24 hour Deadline... THE WORST... I will be asking our customer to start using a different Carrier. DHL is Terrible!!!
