No communication

My son sent a parcel of gifts from the UK on about the 4th of July. DHL call me to tell me that it needs to be cleared by customs. I pay the duties on the gift and wait for the parcel to be delivered. A week later I get another call from them telling me the parcel needs to be cleared by customs. I tell the that I have already paid and I then ask to speak to a manager. This is where the wheels come off. The person on the other end hangs up. I call back several times to speak to someone in charge. In one of the emails I see the name Abbas, however I am told that there is no such person working there. eventually he phones me back with some story that I still don't understand. Why is the parcel of soap and cream being subjected to another bout of customs inspections. That was the last I heard anything from them. They have taken both my son and my money and the parcel not delivered. I am not wasting anymore money trying to call them to find out where my parcel is. So we have lost money and goods because of these people.
