A salesman from Datavo Communications named David Carr came into my office at my place of business. David offered me internet & phone service agreement at $84.99 per month with a one year contract. I accepted because it's less than what I'm paying with AT&T and signed the service agreement. I get my first bill and it's $109.00 per month with a 24 month contract. I come into Datavo Communications headquarters and show them my original service agreement. They will not honor it and tell me I agreed to an additional contract regardless of my original contract. The salesman will not return my calls. They are unethical, and deceptive.
