Not impressed- DHL

My first experience with DHL was fantastic so when I had to use them again I was completely fine with it. I had bought something from over seas and from the same place as my first time using them. A long story short I had to speak to 5 different consultants and I had to send the same redirecting address 2 through regarding the product, I also had to end up fighting with them over the phone as after 3 weeks of waiting for this product and the product being delivered to the wrong address twice already I made sure that someone would be available at the correct address and I had asked the company that the driver please phone me when he is at the gate. They sent me another email saying that no one was available for collection so I phoned yet again and spoke to yet another consultant, at this point the consultant told me that the driver was there and hooted at the gate and left because no one was there and that he was already on his way home and done working, I asked why he did not phone me as requested and they could not answer me. I asked that they turn the driver around and they said they could not do that. I asked to speak to a manager regarding the problem and they said that they would transfer me. While being on hold, my people that were waiting at the address phoned and told me that the delivery just arrived. The consultant took me off hold and said they just got a notification that the delivery was made at which point I asked why they **** to me and said that the guy was there and was already off of work.
