AT&T CallVantage
Telephone service shut off during CallVantage installation

This company is terrible. I started trying to install their telephone service two weeks ago. In spite of asking them not to turn off my regular phone service they did. They can't get my CallVantage service working but turned off my regular phone. Now I am without service and am spending a fortune on the cell phone. They sent a person to look at my system and he hadn't a clue what to do. What a horrible company. Useless and costing me a fortune.
