Lack of Cooperation

I have been trying to customs clearance service for about 2 days now and there is still no response, I sent a gift to one of my friends in South Africa from UK and apparently it has been stuck at custom clearance for about 4 days now. I tried contacting the Customs clearance service through the following email address [Email Removed] but there has been no response yet. The only thing I received was an invoice which is of no help unless I can confirm some banking information with them so I can make the custom charges payment. I am very disappointed with the service for it is taking forever to process my enquirers and can someone please tell me why am I being charged for Disbur*****t additionally? Have I not already paid for the delivery of the item?<br> <br> The costumer service is very hectic and uncooperative, I have chased everyone for days now yet they cannot get my package through a simple process to get it done with!<br> <br> I am not satisfied with DHL services at all! Can someone please approach my issue ASAP for I do not want the delivery to be stuck in Customs clearance forever!
