Shockingly Bad service and communication

My internet service provider sent me 2 SIM cards that needed to be delivered. They had to be delivered to me in person. However, I couldn't take delivery as I drive around from client to client. I phoned CCD Couriers to make arrangements for my wife to pick them up at her place of work. Myself and CCD spoke numerous times about what documents we needed to produce for my wife to take delivery. When the delivery driver came, he refused to give us the SIM cards. We explained that there was an arrangement made and that he should just phone his superiors to clarify the situation. He was arrogant and said he makes the decision and will not give the SIM cards. After my wife provided all the documents CCD Couriers asked for, including the letter I wrote giving her permission to pick up the SIM cards, I had to phone CCD Couriers and was furious about the bad service. We did what we were told we should do, and still, they did not give us the SIM cards. In the end I got the sim but it was not the effort and the whole experience was shockingly bad. The people in the call center doesn't update the delivery people notes and the delivery people think they are the boss of the company.
