Still not working after 2 weeks

Over the past 14 days I have had extremely frustrating service regarding my Adsl fault I logged. Every time I call in there is a different reason or escalated to different department. Twice I have waited at home for a technician to come but none pitched up. This is extremely unprofessional. Today, on day 9, the contact Centre does a router test which shows they do not know what is happening. This should of been done on day 1. They have said it could be a cable fault but no one telling me when it is going to be fixed. The call Centre keep telling me there is nothing they can do. This is unacceptable and unprofessional
