SADV WORST SERVICE

They came to install my router,the installation gentleman was very nice ,said that it would come on in a few hours, 2 hours later I called and said that it is still not on ,at which a lady said they have suddenly started maintenance and I would have to wait another day ,but latest 12 it would be on, at 2 I called again and the tech guy was apparently in a meeting, I'm sitting now without an active line. The consultants all say they will contact you back once they have more info no one does. Honestly the worst service I have ever received.
