Bad customer service

A family member app**** for an ADSL line for the house we live in over three weeks ago. However the job has still not been completed. The first time a technician visited our residence, he did not have a key for a manhole outside the complex. To which he rearranged to come a week later. Today a technician came out and connected the line, however did not have a modem. He assured me that he would bring one over later on, which he did not. My complaint is that surely technicians should make sure they have all that they need in order to complete a job, before they make arrangements with customers. This has become a real inconvenience, as I have to keep making arrangements to be at home.
