Poor service

I canceled my service with Rain. They said they will pick up the router (as far as threatening if we do not give it back they will deduct the money for the router) No 1 when they phone they do not have our correct address. No2 they come to the house during the day (after they got the address right), everybody at work. They cannot phone for arrangements to pick it up at work 5blocks away. What the F can this company do right they give poor service and then they want to start threatening!!!!
