CCD Couriers - NOT CUSTOMCENTRIC AT ALL!

My partner upgraded his rain router to the latest one and paid for it. He is a Personal Trainer that has back to back clients. CCD Couriers called him and he mentioned that he could not take the call. He was then told that he needed to get an affadavit that day from the polce station. How could he possibly do that on the same day that he needed the router? I then called rain and told them the entire challenge and even changed the delivery address with Rain . The lady I spoke to said she understood the challenge and would escalate the matter to the couriers including changing the address. The couriers once again kept calling him the following day trying to deliver the router to the unchanged address. No one was there. I called them to tell them that they are meant to deliver it to me. They absolutely refused to deliver to me. I dont understand why there is no exception. He has paid and he wants his router. The service we have received from CCD Couriers is really bad. We still dont have the router and there has been no sign on wanting to get this delivered. How do we get somethig from these people that has been paid for?
