Unable to get contact number active

Two weeks ago I've received a fixed line lookalike phone and trying to get the number activated so that I can set up my internet is a mission.I have now called on numerous occasions to the 10210 number,*** number ,no luck.I'm getting desperate now and think it would be the best to cancel this contract as I'm unable to get this number active as I'm getting shuffled from pillar to post from agent to agent who thinks another department will be able to assist,not counting how long I,ve been holding on for a agent because of the long queue volumes.
