I did not sign with them. The sales person at my door insisted to see my bill. After repeating 3 times I would hear his offer, but without giving or showing my bill to him, he left. His answer was :"The only thing I can do with your bill is to pay it". It doesnt matter. It is my personal information and I dont want to share it. So what? I can say they have at least awful customer service.
