Liars, Can't cancel, they don't follow up

First one of the sales person showed up on my door, and told me that they send me a message at the back of my ConEdison bill, for me to confirm with them in order to receive my benefits. Then I looked at my bill, and it said something about New York state renewable energy. He acted as if they are the only New York state energy provider. After I asked millions of times, he changed the statement to : " We are the only New York based energy provider, your delivery charges would be a lot higher if you get it from another state." Through out the whole time, he acted as if he is working for New York State Government. I asked many times, if they are the only company who is New York based, and he kept on saying , " yes" if you don't want to get it from us, you can sign up with New Jersey, when you are eligible for it. While we were having this discussion, 2 other guys showed up on my door. This made me really uncomfortable, since I didn't receive any calls before hand about this visit, and I was in my home clothes. Honestly, when I was opening my door, I thought they came from Con Edison to check the meter, they always come for 1 minute, check it and leave. Then they have me on the phone, to confirm with them, while he was showing me stuff with gestures, while the other ones were watching me, because apperantly they wouldn't be able to confirm over the phone, if they hear him speaking. After I asked many times about their cancellation policy, I was told repeatedly I can cancel at any time after they process it. If I want to cancel before they process it , I would have to call them within 3 days after I sign. I don't sign anything before reading it. Throughout the whole time, when I was reading long paper, that they want me to sign, they kept on talking, and telling me stories in order to confuse me. I warned them couple of times to be quiet, so that I can focus on reading it, but this time they kept on talking among each other. They kept on telling me all of my neighbors have already signed up for the benefits, and they can't believe I haven't done so yet. I finally signed the damn thing, just to get rid of them, after reading that I can cancel within 3 days.
Right after I signed, they rang the door bell of my neighbor. I didn't make a discussion about it, and just closed my door. They are such liars, and they don't know how to stick with their lies either. First he told me my next door neighbor , the upstairs, everybody else signed up for it, and then he rang the door bell of my next door neighbor. I went up to my laptop, typed the company's name, saw lots of complaints about this company, and saw that he and the other 2 guys lied to me repeatedly , when I asked them if they are the only New York based company. They are not the only ones apparently.
I called the company back right away, and told them that I just signed up for this thing and want to cancel it right away. I spoke to Samantha (extension 308), and she told me she can't cancel it right now, since she doesn't have the paper yet, and told me that she will cancel it once she receives the paper that I signed. I asked her repeatedly, how do I know that she will cancel it later. I asked her if she could give me a confirmation. She told me she can't give me a confirmation right now, and after I really insisted, she told me she could call me back within 3 days to let me know that it's cancelled. Then I asked her , how do I know that she would really call me. She told me that, if I want I could also call her back from her extension 308.
Of course, like I guessed she didn't call me within 3 days to confirm, so I call her back, she didn't reply to her extension. I called the regular number and waited for the sales department, and she picked up the phone. There is only one person working I guess on their sales department. I reminded her about our phone call. First she couldn't find my file in the system, and then she said my application is pending. Then I told her I don't have the time , to call them back and forth, to see if they cancelled it or not, and told her that she should call me back once it's processed. This time, she told me, she doesn't do that. I reminded her that she can look back at their company's phone call recordings, when she said clearly that she would call me back, when I called her the first time. I guess the ability of lying is one of the requirements, when they are getting hired for this company. I asked to talked to her supervisor. She had me on hold, and then told me nobody is available to talk to me right now. I asked her how long would I have to wait on hold, in order for the supervisor to talk to me, she replied, it might take a week. I told her that this is ridiculous, and demand that her supervisor call me right away, and gave her my phone number once again, although she has it on my application.
I'm pretty sure that nobody will call me.
DON'T GET INVOLVED WITH THESE PEOPLE, YOU WILL EITHER LOOSE YOUR TIME OR MONEY, OR MOST PROBABLY BOTH! In fact, don't sign anything, for any company shows up on your door, it's so sketchy, and their sales people kept on telling me that the company will call me back within 3 days to ask me one more time, and if I answer one of their questions wrong, these guys might get fired. What kind of pressure is that, these people know my address. This is soooooooo sketchy.
