Crooked company!!

I also a client of Merchants' Choice payment solutions. First I receive a call from Merchants' Choice giving me an appointment date to talk with Karen Ferro ( Merchants' Choice representative ).I meet with her one day and she said they can save $40 or more every month. But i don't want contract so I said no, so she told me there are won't be any contract. She also give my business a good rate compare to what i have. After she give me a paper to sign and take off saying she will be back in 10 minute to give me the copy. I wait until time to close and she don't come back. 2 week later they call me to install that is when I could speak to Karen. Karen toke my equipment and go to get it install. She come back the next day and tell me the equipment is broken. I have to get a new one from them. After with Merchants' Choice for one month, when i receive the first statement it was way higher then my previous merchant. So i call customer service. They told me to speak with Karen. Now i can't even find her or call he, because Karen don"t even pickup the phone.Now I just found out that i do have a contract and if i cancel my service i have to pay them $450.
any one want to know more about them please call me at 7169079101. My name is Tim. and i have all the prove to show you how ripoff they can be.
