Insight Pest Solutions review: Scam rip off

I had a sales person visit my one. I will say he was congenial. But I have since learned that ther company did not have the license to be door to door selling, it requires a bond. Anyway, the service didn't stop any of the insects from coming in my home and when they came back for a follow up, they didn't even go in my back yard where 3/4 of my home is exposed. When I told them I wanted to end the contract, they told me t here was a $300.00 fee to end the agreement. I did not receive a signed copy of their "conract". So, now they are telling me that they will turn me over to collections if I don't pay up. Dont get sucked into this scam! The product they market doesn't work and they show their true colors when you let them know you will not be a victim of their scams any more. I am considering sueing them for the $297.00 that I have already paid them. (sorry for the caps, but they really need to be investigated)
